New and known 5-[(2H-pyrrol-2-ylidene)methyl]-2,2'-bi-1H-pyrrole derivatives, having immunomodulating activity and, represented by the following general formula (I)
wherein, subject to a proviso, R1 represents hydrogen, phenyl, C1-C20 alkyl or C2-C20 alkenyl, wherein the alkyl and alkenyl groups may be unsubstituted or substituted by 1 to 3 substituents chosen independently from halogen, C1-C6 alkoxy, hydroxy, aryl and aryloxy; R2 represents hydrogen, C1-C6 alkyl, cyano, carboxy or (C1-C6 alkoxy) carbonyl; R3 represents halogen, hydroxy or C1-C11 alkoxy unsubstituted or substituted by phenyl; R4 represent hydrogen, C1-C6 alkyl or phenyl; each or R5 and R6 independently represents hydrogen, C2-C20 alkanoyl, C3-C20 alkenoyl, phenyl, C1-C20 alkyl or C2-C20 alkenyl, wherein the alkanoyl, alkenoyl, alkyl and the alkenyl groups may be unsubstituted or substituted by 1 to 3 substituents chosen independently from halogen, C1-C6 alkoxy, hydroxy, aryl, aryloxy, cyano, carboxy, (C1-C6 alkoxy)carbonyl, (C3-C4 alkenyl)carbamoyl, aralkylcarbamoyl, arylcarbamoyl and -CONRcRd in which each of Rc and Rd independently is hydrogen or C1-C6 alkyl or Rc arid Rd, taken together with the nitrogen atom to which they are linked, form a morpholino or piperidino ring; or two of R4, R5 and R6 taken together form a C4-C12 polymethylene chain, which can be unsubstituted or substituted by a C1-C12 alkyl, by a C2-C12 alkenyl or by a C1-C12 alkylidene group, wherein the alkyl, alkenyl and alkylidene groups may be in turn unsubstituted or substituted by a substituent chosen from halogen, C1-C6 alkoxy, hydroxy, cyano, carboxy, (C1-C6 alkoxy)carbonyl, aryloxy and aryl; the remaining one being hydrogen or C1-C12 alkyl; and the pharmaceutically acceptable salts thereof, are disclosed.
