Syntheses and exploration of new biological activities in ethyl 6/7-substituted and 6, 7-disubstituted quinolin-4-one-3-carboxylates
摘要:
Syntheses of a number of ethyl 1H, 4H-quinolin-4-one-3-carboxylates carrying substituted piperidinedione ring at position 6 (25 & 31-35), tetrahydrofuranone (37) or tetraydropyridazinone ring (39) at position 7 and hydroxy and hydroxymethyl substituents at positions 6 and 7 respectively (41) of the quinolone ring, are reported here, of these compounds on the in vitro heme polymerase activity of Plasmodia and on the in vitro fungal growth are described.
This disclosure describes compositions of matter useful as anxiolytic agents and the method of meliorating anxiety in mammals therewith; the active ingredients of said compositions of matter being certain substituted 6-phenyl-1,2,4-triazolo[4,3-b]pyridazines or the pharmacologically acceptable acid-addition salts thereof.

This paper reports on the synthesis and pharmacological activity of 6-aryl-4,5-dihydro-3(2H)-pyridazinone derivatives. The compounds exhibit an aggregationinhibiting action on human platelets in vitro and on rat platelets under ex vivo conditions, as well as a hypotensive action on rats. The strongest pharmacological effects were found with dihydropyridazinones, which have a 6-[p-[(chloroalkanoyl)amino]phenyl]
