Medicament being useful as a fibrosis inhibitor for organs or tissues, which comprises a compound of the formula (I):
wherein Ring Z is optionally substituted pyrrole ring, etc.; W2 is -CO-, -SO2-, optionally substituted C1-C4 alkylene, etc.; Ar2 is optionally substituted aryl, etc.; W1 and Ar1 mean the following (1) and (2):
(1) W1 is optionally substituted C1-C4 alkylene, etc.; Ar1 is optionally substituted bicyclic heteroaryl having 1 to 4 nitrogen atoms as ring-forming atoms:
(2) W1 is optionally substituted C2-C5 alkylene, optionally substituted C2-C5 alkenylene, etc.; and
Ar1 is aryl or monocyclic heteroaryl, which is substituted by carboxyl, alkoxycarbonyl, etc. at the ortho- or meta-position thereof with respect to the binding position of W1,
or a pharmaceutically acceptable salt thereof.
The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof.
The formula I compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2, FGFR-1, PDGFR, HER-1, HER-2, thereby making them useful as anti-cancer agents. The formula I compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.

Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure–activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of
