Description
WO 91/04025 PCl /G B90/0 1412 2 ~ 65 ~2 i NOVEL MACROCYCLIC COMPOUNDS AND NOVEL METHOD OF TREATMENT
This invention relates to novel pharmaceutical uses of certain known macrocyclic compounds, and to novel - macrocyclic compounds which have the same novel utility.
European patent application No 184162 (to Fujisawa Pharmaceuticals Co Ltd) discloses several raacrocyclic compounds which are derivatives of 12-(2-cyclohexyl-l-methylvinyl)-13,19,21,27-tetr~methyl-11,28-dioxa-4-azatricyclo[22.3.1.04~9]octacos-18-ene (numbered 1~ FR-900506, FR-900520, FR-900523 and FR-900525) and which are isolated from microorganisms belonging to the genus Strep~omvces. The macrocyclic compounds and a numbPr of their derivatives are indicated as immunosuppressive agents.
International patent application No WO 89/05304 (also European Patent application No 323042, both to Fisons plc) discloses a large number of macrocyclic compounds which may ' :
be derived from those disclosed in European patent application No 184162. Again, the compounds are primarily 20 indicated as immunosuppressive agents.
European patent applications Nos 349049 and 349061 (both to Merck & Co Inc) each disclose a macrocyclic compound which is indicated as an immunosuppressive agent.
The compounds and methods disclosed in the patent 25 applications mentioned above may be used in the production of the novel compounds of the pr~osent invention.
Alternatively, the novel compounds may be produced by total synthesis.

2 ~ - 2 - --, We have now found a novel group of macxocyclic compounds which act as antagonists of immunosuppressive compounds, particularly macrocyclic immunosuppressive compounds including derivatives of 5 12-(2-cyclohexyl-1-methylvinyl)--13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo~22.3.:1.04~9]octacos-1~-ene and rapamycin, as shown in the mixed lymphocyte reaction (MLR) (des~ribed in WO 89/05304, Exampl~ A). The novel group of compounds are therefore useful inter alia in the treatment 10 f immunodepression or. a._ disorder involving immunodepression.
Thus, according to the present invention, there is provided the use of a compound of formula I, H0~

R3 represents methyl optionally substitutPd by -CO2H or an ester or amide thereof; ethyl optionally substituted by O, OH or -CO2H or an ester or amide 5 thereof; propyl optionally substituted by OH or O; or allyl optionally substituted by OH;
R4 represents H;

R9 represents OH or OCH3;

in addition to their significances above Rl and R5 may together represent an oxygen atom, in which case R6 and R7 together rPpresent a second 20 carbon-carbon bond between the carbon atoms to which they are attached;
R7 and R8 may together represent an oxygen atom;
and R3, R4 and Y, together with the carbon atoms to which they are attached, may represent a methyl-substituted furanyl ring:

then R7 represents OH; and 5 ii) when n is 1, then R3 is not methyl or ethyl;
in the manufacture of a medicament for the treatment of immunodepression or a disorder involving immunodepression.
Examples of disorders involving immunodepression ~ 10 include AIDS, cancer, senile dementia,~~trauma (including wound healing, surgery and shock), chronic bacterial infection, and certain central nervous system disorders.
The immunodepression to be treated may be caused by an overdose of an immunosuppressive macrocyclic compound, for 1~ example derivatives of 12-(2-cyclohexyl-1-methylvinyl)-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo [22.3.1.04~9]octacos-18-ene such as FR-900506, or rapamycin. Overdosing of such medicaments by patients is quite co~mon upon their realising that they have forgotten 20 to tak2 their medication at the prescribed time, and can lead to serious side effects.
A further situation in which the compounds of formula I may be used to treat immunodepression is in vaccination.
It is sometimas found that the antigen introduced into the 25 body for the acquisition of immunity from disease acts as an immunosu;ppressive agent, and so antibodies are not produced by the body and immunity is not acquired. By introducing a compound of formula I into the body (for WO91/0402~ PCT/~B90/01412 - 5 - 2 0 65~
example in the vaccine) the und2sired immunosuppression may be overcome and immunity acquired.
The pr~sent invention further provides the novel compounds of formula I, as defined above, provided that 5 i) when Rl represents OH; R2 represents H; R5 and R6 together represent a sPcond carbon-c~rbon bond between the carbon atoms to which they are attached; R7 represents H; R9 represents OCH3; X and Y each represent O; and n represents 2; then R3 does not 10 represent 2-oxopropyl, 2,3-dihydroxypropyl or ethanalyl;
ii) when Rl rPpresents OH; R2 repres~nts H; R5 and R6 tosether repr~sent a second carbon-carbon ~ond between the carbon atoms to which they are attached; R7 represents OH; R9 represents OCH3; X and Y each 15 rePresent o and n represents 2; then R3 does not represent allyl or l-hydroxyprop-2-enyl; and iii) when Rl represents OH; R2 represents H; R~ and R6 together represent a s~cond carbon-carbon bond between the carbon atoms to which they are attached; R7 repre~ents H: R9 represents OCH3; X and Y each represent (H,OH); and n represents 2; then R3 does not represe~t allyl.
In the novel use or the novel compounds, we prefer R3 to be ethyl substituted by O or propyl substituted by 25 o.
Desirab].y, R7 is OH.
We prefer R2 to be OH, more preferably (S)-OH (ie to have S absolute stereochemistry at its point o~ ~ttachment :: -;.
WO91/04025 PCT/GB90/0l4l2 2~5~2~ - 6 -. to the molecule).
When R3 comprises an ester or amide group, we prefer the alcohol or amine moiety to contain from 1 ~o 10 carbon atoms, for example the alcohol moiety may be methanol.

This invention relates to novel pharmaceutical uses of certain known macrocyclic compounds, and to novel - macrocyclic compounds which have the same novel utility.
European patent application No 184162 (to Fujisawa Pharmaceuticals Co Ltd) discloses several raacrocyclic compounds which are derivatives of 12-(2-cyclohexyl-l-methylvinyl)-13,19,21,27-tetr~methyl-11,28-dioxa-4-azatricyclo[22.3.1.04~9]octacos-18-ene (numbered 1~ FR-900506, FR-900520, FR-900523 and FR-900525) and which are isolated from microorganisms belonging to the genus Strep~omvces. The macrocyclic compounds and a numbPr of their derivatives are indicated as immunosuppressive agents.
International patent application No WO 89/05304 (also European Patent application No 323042, both to Fisons plc) discloses a large number of macrocyclic compounds which may ' :
be derived from those disclosed in European patent application No 184162. Again, the compounds are primarily 20 indicated as immunosuppressive agents.
European patent applications Nos 349049 and 349061 (both to Merck & Co Inc) each disclose a macrocyclic compound which is indicated as an immunosuppressive agent.
The compounds and methods disclosed in the patent 25 applications mentioned above may be used in the production of the novel compounds of the pr~osent invention.
Alternatively, the novel compounds may be produced by total synthesis.

2 ~ - 2 - --, We have now found a novel group of macxocyclic compounds which act as antagonists of immunosuppressive compounds, particularly macrocyclic immunosuppressive compounds including derivatives of 5 12-(2-cyclohexyl-1-methylvinyl)--13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo~22.3.:1.04~9]octacos-1~-ene and rapamycin, as shown in the mixed lymphocyte reaction (MLR) (des~ribed in WO 89/05304, Exampl~ A). The novel group of compounds are therefore useful inter alia in the treatment 10 f immunodepression or. a._ disorder involving immunodepression.
Thus, according to the present invention, there is provided the use of a compound of formula I, H0~

R3 represents methyl optionally substitutPd by -CO2H or an ester or amide thereof; ethyl optionally substituted by O, OH or -CO2H or an ester or amide 5 thereof; propyl optionally substituted by OH or O; or allyl optionally substituted by OH;

in addition to their significances above Rl and R5 may together represent an oxygen atom, in which case R6 and R7 together rPpresent a second 20 carbon-carbon bond between the carbon atoms to which they are attached;
R7 and R8 may together represent an oxygen atom;
and R3, R4 and Y, together with the carbon atoms to which they are attached, may represent a methyl-substituted furanyl ring:

then R7 represents OH; and 5 ii) when n is 1, then R3 is not methyl or ethyl;
in the manufacture of a medicament for the treatment of immunodepression or a disorder involving immunodepression.
Examples of disorders involving immunodepression ~ 10 include AIDS, cancer, senile dementia,~~trauma (including wound healing, surgery and shock), chronic bacterial infection, and certain central nervous system disorders.
The immunodepression to be treated may be caused by an overdose of an immunosuppressive macrocyclic compound, for 1~ example derivatives of 12-(2-cyclohexyl-1-methylvinyl)-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo [22.3.1.04~9]octacos-18-ene such as FR-900506, or rapamycin. Overdosing of such medicaments by patients is quite co~mon upon their realising that they have forgotten 20 to tak2 their medication at the prescribed time, and can lead to serious side effects.
A further situation in which the compounds of formula I may be used to treat immunodepression is in vaccination.
It is sometimas found that the antigen introduced into the 25 body for the acquisition of immunity from disease acts as an immunosu;ppressive agent, and so antibodies are not produced by the body and immunity is not acquired. By introducing a compound of formula I into the body (for WO91/0402~ PCT/~B90/01412 - 5 - 2 0 65~
example in the vaccine) the und2sired immunosuppression may be overcome and immunity acquired.
The pr~sent invention further provides the novel compounds of formula I, as defined above, provided that 5 i) when Rl represents OH; R2 represents H; R5 and R6 together represent a sPcond carbon-c~rbon bond between the carbon atoms to which they are attached; R7 represents H; R9 represents OCH3; X and Y each represent O; and n represents 2; then R3 does not 10 represent 2-oxopropyl, 2,3-dihydroxypropyl or ethanalyl;
ii) when Rl rPpresents OH; R2 repres~nts H; R5 and R6 tosether repr~sent a second carbon-carbon ~ond between the carbon atoms to which they are attached; R7 represents OH; R9 represents OCH3; X and Y each 15 rePresent o and n represents 2; then R3 does not represent allyl or l-hydroxyprop-2-enyl; and iii) when Rl represents OH; R2 represents H; R~ and R6 together represent a s~cond carbon-carbon bond between the carbon atoms to which they are attached; R7 repre~ents H: R9 represents OCH3; X and Y each represent (H,OH); and n represents 2; then R3 does not represe~t allyl.
In the novel use or the novel compounds, we prefer R3 to be ethyl substituted by O or propyl substituted by 25 o.
Desirab].y, R7 is OH.
We prefer R2 to be OH, more preferably (S)-OH (ie to have S absolute stereochemistry at its point o~ ~ttachment :: -;.
WO91/04025 PCT/GB90/0l4l2 2~5~2~ - 6 -. to the molecule).
When R3 comprises an ester or amide group, we prefer the alcohol or amine moiety to contain from 1 ~o 10 carbon atoms, for example the alcohol moiety may be methanol.
