Description

TECHNICAL FIELD

The present invention relates to 2-amino-1,3-propanediol compounds useful as pharmaceuticals, particularly as an immunosuppressant.

BACKGROUND ART

In recent years, cyclosporin is in use for suppressing rejection developed in transplanting organs. Inclusive of the compounds currently under development, the so-called immunosuppressants are expected to be useful as therapeutic agents for articular rheumatism and so on. Said cyclosporin, however, also poses problems of side effects such as renal disorders.

Meanwhile, Japanese Patent Unexamined Publication No. 104087/1989 discloses that an immunosuppressive substance is obtained from a liquid culture of Isaria sinclairii and said substance has been confirmed to be (2S,3R,4R)-(E)-2-amino-3,4-dihydroxy-2-hydroxymethyl-14-oxoicosa-6-enoic acid of the formula ##STR2## disclosed in U.S. Pat. No. 3928572. In addition, Japanese Patent Unexamined Publication No. 128347/1991 states that a series of said compound has an immunosuppressive action.

Referring to Merck Index, 11th edition, it is described that 2-amino-2-methyl-1,3-propanediol (Index No. 460), 2-amino-2-ethyl-1,3-propanediol (Index No. 451) and 2-amino-2-hydroxymethyl-1,3-propanediol (also called tromethamine, Index No. 9684) can be used as surfactants, intermediates for pharmaceuticals, emulsifiers or gas adsorbents and that tromethamine is medically usable as an alkalization agent. In Japanese Patent Unexamined Publication No. 416/1987, a hair dye containing 2-amino-2-(C1-C5 alkyl)-1,3-propanediol is disclosed. U.S. Pat. No. 4,910,218 and J. Med. Chem., vol. 33, 2385-2393 (1990) teach 2-amino-2-(methyl or ethyl)-1,3-propanediol as an intermediate for an antitumor agent. Also, Japanese Patent Unexamined Publication No. 192962/1984 teaches that the aforementioned 2-amino-2-(C1-C5 alkyl)-1,3-propanediol or 2-amino-1,3-propanediol can be used as a stabilizer for an antigen or antibody-sensitized latex reagent. Moreover, U.S. Pat. No. 3,062,839 teaches 2-methyl- or ethyl-amino-2-(furylmethyl, phenylmethyl or phenylmethyl substituted by lower alkyl, lower alkoxy, chloro, hydroxy or unsubstituted amine)-1,3-propanediol having a tranquilizer action and J. Org. Chem., vol. 25, 2057-2059 (1960) teaches 2-methylamino-2-(phenylmethyl or phenylmethyl substituted by 2-methyl, 3-methyl, 4-methyl, 4-methoxy or 4-hydroxy)-1,3-propanediol. It is not known, however, that these compounds have immunosuppressive actions such as suppression of rejection developed in organ transplantation, prevention and treatment of autoimmune diseases and the like.

An object of the present invention is to provide novel 2-amino-1,3-propanediol compounds having superior immunosuppressive action with less side effects.

Of the Compounds (XXXXXII), a compound wherein Rr is an alkyl which may have a double bond or carbonyl in the chain, such as heptadecyl, is produced, for example, by fermentation or by using a compound (XXXXXIII) produced by the fermentation and having the formula ##STR436## as a starting material. Examples of the microorganism capable of producing the compound (XXXXXIII) include those belonging to Ascomycetes or Fungi Imperfecti, particularly the genera Isaria and Mycelia belonging to the Fungi Imperfecti and the genus Myriococcum (the genus Thielavia) belonging to Ascomycetes, which are respectively deposited at American Type Culture Collection as Isaria sinclairii ATCC No. 24400, Myriococcum albomyces ATCC No. 16425 and Mycelia sterilia ATCC No. 20349. Also, Myriococcum albomyces ATCC No. 16425 has been deposited at the Institute of Fermentation, Osaka as IF032292.

Compound (XXXXXIII) can be produced, for example, by a mutant strain obtained by mutating the above-mentioned strain by a conventional artificial mutating method using ultraviolet rays, high frequency radiation, drug or the like.

C. for the microorganisms belonging to the genus Myriococcum or Mycelia.

The Compound (XXXXXIII) produced in the culture medium is isolated therefrom by conventional steps such as extraction and adsorption which may be used in combination as necessary. For example, in the case of a microorganism belonging to the genus Isaria such as Isaria sinclairii, the Compound (XXXXXIII) is taken out from the culture by filtering off the insoluble matters such as cells from the culture, isolation by centrifugation, passing the culture filtrate through Amberlite XAD-2 (trade mark) and adsorbing Compound (XXXXXlII). The Compound (XXXXXIII) thus obtained is eluted with, for example, methanol and the eluate is fractionated by reversed phase chromatography, whereby a highly purified product of Compound (XXXXXlII) can be obtained. In the case of a microorganism belonging to the genus Myriococcum or the genus Mycelia, such as Myriococcum albomyces, Mycelia sterilia or the like, cells are separated from the culture by filtration, centrifugation and the like and the culture filtrate is treated in the same manner as in the case of the microorganisms belonging to the genus Isaria. The Compound (XXXXXIII) is extracted from the separated cells by the use of methanol and the extract is treated with Amberlite XAD-2 in the same manner as with the filtrate above and purified by chromatography and recrystallization.

The action and effect of the present invention are explained in detail by illustrating experimental examples in the following.

For determining the immunosuppressive activity, various immune reactions using lymphocytes of mouse, rat or human are usable. It may be determined with high sensitivity, for example, by an allogenic mixed lymphocyte reaction (allogenic MLR) of mouse, rat or human.

The allogenic MLR is a blastogenesis of lymphocytes induced by a mixed culture of lymphocytes derived from two kinds of cells which are allogenic but have different major histocompatibility antigens, such as spleen cells, lymph node cells and peripheral blood lymphocytes. The allogenic MLR is a phenomenon induced by and reflects the difference in major histocompatibility antigens of the donors of the lymphocytes, and a blastogenesis phenomenon of the lymphocytes is not developed by a mixed culture of the lymphocytes from monozygotic twins. Accordingly, allogenic MLR is widely used for the donor-recipient selection in organ transplantations.

When allogenic MLR is desired, one way-MLR, wherein the lymphocytes of one of them are used as stimulator cells upon X-ray irradiation or treatment with mitomycin C to inhibit proliferation and the blastogenesis of the other lymphocytes (responder cells) is determined, may be used.

Further, the immunosuppressive activity may be determined as an activity to inhibit induction of cytotoxic T cells having the major histocompatibility antigen restrictive property during allogenic MLR.

Also, the immunosuppressive activity may be determined, besides allogenic MLR, as an activity to inhibit the blastogenesis of the lymphocytes induced by the stimulation of various mitogens such as concanavalin A, phytohemaggulutinin and pokeweed mitogen or as an activity to inhibit the proliferation of the lymphocytes induced by a cytokine (e.g. interleukin 1, 2, 3, 4, 5 or 6) having an activity to reinforce the proliferation or promote the differentiation of the lymphocytes such as T cells or B cells, or manifestation of such function. In addition, it is possible to evaluate the immunosuppressive activity according to the inhibition of the production of these cytokines from T cells or macrophages.

Alternatively, the activity may be evaluated as an activity to inhibit induction of allogenic cells-specific cytotoxic T cells induced in spleen cells of mouse previously immunized with, for example, allogenic cells by intraperitoneally, orally, intravenously, intradermally, subcutaneously or intramuscularly administering a compound to mice; as an activity to inhibit the production of an allogenic cells-specific antibody produced in the blood serum of mouse immunized with allogenic cells or the like; or as an activity to inhibit rejection on organ transplantation between allogenic mice, rats, dogs and so on, graft-versus-host reaction, or delayed type allergy and adjuvant arthritis.

Moreover, the immunosuppressive activity may be evaluated as an activity to inhibit, for example, production of an anti-DNA antibody, production of a rheumatoid factor, nephritis, abnormal proliferation of lymphocytes or urinary protein; or a macrobiotic effect by the administration of the compound to MRL/lpr mouse, NZB/WFx mouse, BXSB mouse, NOD mouse and the like which are model animals with autoimmune diseases.

Experimental Example 1 (inhibition of allogenic mixed lymphocyte reaction in mouse)

The mouse allogenic mixed lymphocyte reaction (hereinafter referred to as mouse allogenic MLR) is carried out by a mixed culture of spleen cells of BALB/c mouse as responder cells and spleen cells of C57BL/6 mouse treated with mitomycin C as stimulator cells at the same ratio.

The reaction cells are prepared as follows. A spleen is removed from a 5-6 weeks old BALB/c mouse and a single cell suspension of spleen cells is obtained by the use of an RPMI1640 medium (containing kanamycin sulfate 60 .mu.g/ml, penicillin G potassium 100 units/ml, N-2-hydroxyethylpiperazine-N'-2-ethanesulfonate 10 mM, 0.1% sodium hydrogencarbonate and L-glutamine 2 mM) supplemented with 5% heat-inactivated fetal calf serum (hereinafter referred to as FCS). After hemolysis treatment, the suspension is adjusted to a concentration of 10.sup.7 cells/ml by the use of an RPMI1640 medium containing 10.sup.-4 M 2-mercaptoethanol and 10% FCS and used as a reaction cell suspension.

The stimulator cells are prepared as follows. A spleen is removed from a 5-6 weeks old C57BL/6 mouse and a single cell suspension of spleen cell is obtained by the use of an RPMI1640 medium. After hemolysis treatment, the suspension is treated with 40 .mu.g/ml mitomycin C at 37.degree. C. for 60 minutes. After washing three times, the suspension is adjusted to a concentration of 107 cells/ml by the use of an RPMI1640 medium containing 10.sup.-4 M 2-mercaptoethanol and 10% FCS and used as a stimulator cell suspension.

The responder cell suspension (50 .mu.l) prepared by the method described above,-the stimulator cell suspension (50 .mu.l) prepared by the method described above and a test sample (100 .mu.l) prepared by the use of an RPMI1640 medium containing 10% FCS are placed in a 96 well flat-bottomed micro testplate and cultured at 37.degree. C. under 5% CO.sub.2 -95% air for 4 days.

The blastogenesis reaction of lymphocytes in mouse allogenic MLR is determined by a method using .sup.3 H-thymidine uptake as an index. Namely, after the culture, .sup.3 H-thymidine 18.5 KBq/well is added and the cells are cultured for 4 hours. The cells are collected by a cell harvester and the radioactivity incorporated into the cells is determined by a liquid scintillation counter and used as an index for the lymphocyte blastogenesis in mouse allogenic MLR. The inhibition of mouse allogenic MLR is calculated by the formula below and evaluated accordingly.

Of the compounds of the present invention, the preferred show an IC.sub.50 value (a concentration to inhibit by 50%) of from about 1 nM to about 50 nM in a mouse allogenic mixed lymphocyte reaction. ##EQU1## Experimental Example 2 Inhibition of proliferation of interleukin 2 (IL-2)-dependent mouse T cell line CTLL-2 induced by IL-2!

An IL-2-dependent mouse T cell line CTLL-2 is prepared to a concentration of 2.times.10.sup.5 cell/ml in an RPMI1640 medium containing 10% FCS. A cell suspension thereof (50 .mu.l), recombinant human IL-2 (rh-IL-2) 40 U/ml (50 .mu.l) and a test sample (100 .mu.l) prepared by the use of an RPMI1640 medium containing 10% FCS are placed in a 96 well flat-bottomed micro testplate and cultured at 37.degree. C. under 5% CO.sub.2 -95% air for 68 hours. After the culture, 100 .mu.l of the supernatant of each well is removed and a 5 mg/ml MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide! solution is added to each well by 20 .mu.l and the cells are incubated at 37.degree. C. for 4 hours. Then, 0.01N hydrochloric acid solution (100 .mu.l) containing 10% sodium dodecyl sulfate is added thereto and the cells are incubated at 37.degree. C. overnight. The purple formazan crystals produced are dissolved and the absorbance at 570 nm is measured using a microplate absorbance photometer and used as an index of-the proliferation of the IL-2-dependent CTLL-2 cells. The inhibition (%) of the IL-2 dependent proliferation is calculated by the following formula.

Of the compounds of the present invention, the preferred show an IC.sub.50 value (a concentration to inhibit by 50%) of from about 1 nM to about 50 nM in the IL-2-dependent proliferation of mouse T cell line CTLL-2. ##EQU2## Experimental Example 3 (take-prolonging effect on allogenic skin graft in rat)

A full-thickness graft (1.5.times.1.5 cm) of a 4 weeks-old male WKAH rat or LEW rat is grafted to a graft floor on the back of a 4 weeks-old male F344 rat by suture. The graft is covered with a sterile gauze and bound. The bandage is removed 5 days after the grafting and the skin graft is observed daily until it is rejected. The skin graft is considered to be rejected when 90% or more of the epithelium of the skin graft showed necrosis and turned brown. The number of days from the grafting to rejection is taken as a graft taking days. A test compound is intraperitoneally, intravenously or orally administered once a day and 10 times from the grafting day to day 9.

When a test compound is not administered, an average taking days for grafting the skin of a HAH rat to an F344 rat was 6.6.+-.0.5 and that for grafting the skin of an LEW rat to an F344 rat was 8.2.+-.0.4.

Of the compounds of the present invention, a preferred compound showed, when administered at 0.1-10 mg/kg, an average taking days of not less than 10 for grafting the skin of a WKAH rat to an F344 rat and not less than 20 for grafting the skin of an LEW rat to an F344 rat, thus showing a take-prolonging effect statistically significant as compared with the group without administration of the test compound.

Experimental Example 4 (inhibition of adjuvant arthritis in rat)

Dead tuberculosis bacterium (R35H5v-1 strain, 0.5 mg) was suspended as an adjuvant in 1.0 ml of liquid paraffin and innoculated to the tail head of a 10 weeks-old male LEW rat to cause adjuvant arthritis. After the innoculation of the adjuvant, the rats are observed daily to determine the onset of arthritis, ratio of the onset cases and body weight changes. At day 21, swelling of the hind limbs and the weight of the organs are measured. A test compound is intravenously or orally administered from the adjuvant innoculation day once a day and 22 times up to day 21.

When the test compound was not administered, arthritis was found in all 7 rats innoculated with adjuvant at day 9.6.+-.0.5, along with swelling and destruction of the bone of the hind limbs. Along with the onset of the adjuvant arthritis, decrease in body weight, increase in the weights of kidney and adrenal and decrease in the thymus weight were found.

Of the compounds of the present invention, a preferred compound delayed the onset of and decreased the ratio of the onset cases of the adjuvant arthritis to a statistically significant degree and significantly suppressed swelling and bone destruction of the hind limbs by the administration of 0.1-10 mg/kg thereof. In addition, decrease in body weight, increase in the weights of kidney and adrenal and decrease in the thymus weight, which accompany onset of adjuvant arthritis, were significantly reduced.

As is evident from the various experiments inclusive of pharmacological experiments as noted above, the compounds of the present invention and salts thereof have superior immunosuppressive action and are useful as pharmaceuticals.
