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.
