- Synthesis and antibacterial evaluation of novel 2-[N-Imidoylpyrrolidinyl] carbapenems
-
The synthesis, antibacterial activity and DHP-susceptibility of a series of novel carbapenems, directly linked with heterocyclic moiety are described. Especially, the compounds linked pyrrolidine-carbapenem exhibited to have a good antibacterial activity against Staphylococcus aureus (MRSA) as well as Pseudomonas aeruginosa to maintain a good stability towards DHP-I.

- Studies on new platelet aggregation inhibitors 1. Synthesis of 7-nitro-3,4-dihydroquinoline-2(1H)-one derivatives
-
A series of 6-cyclic aliphatic amino-7-nitro-3,4-dihydroquinoline-2(1H)-ones were prepared and tested for platelet aggregation inhibitory effect, cardiotonic activity and chronotropic activity. These compounds appeared to show selective inhibitory activity against platelet aggregation. Among them, 6-(4-ethoxycarbonylpiperidino)-7-nitro-3,4-dihydroquinoline-2(1H)-one (22f) showed the most potent inhibitory activity and high selectivity. A divergent synthetic route to 6-cyclic aliphatic amino-7-nitro-3,4-dihydroquinoline-2(1H)-one derivatives has also been investigated.
