prostacyclin sodium

Epoprostenol sodium (Prostaglandin I2 sodium salt) 是短效血管稀释剂，是一种合成前列环素，可用于研究肺动脉高压和充血性心力衰竭。

Taprostene sodium 是一种部分激动prostacyclin (IP)受体的前列腺素类化合物。它能够与Prostaglandin E2 (PGE2)、ONO-AE1-259 (选择性 EP2 激动剂)及乙酰胆碱相互作用，并显示出显著的心脏保护作用。

Cefminox (Sodium) is a new cephamycin antibiotic possessing a D-amino acid moiety derived from D-cysteine at the C-7B side chain. Cefminox is active against a wide range of bacteria, especially Gram-negative and anaerobic bacteria. Cefminox shows excellent in vivo efficacy (ED50) which is higher than would be expected from its in vitro activity (MIC). Moreover, cefminox possesses more potent activity in suppression of bacterial regrowth than other cephems[1]. Cefminox (Sodium) was the most active beta-lactam, with an MIC at which 50% of isolates are inhibited (MIC50) of 1.0 microg ml and an MIC90 of 16.0 microg ml. Cefminox was especially active against Bacteroides fragilis (MIC90, 2.0 microg ml), Bacteroides thetaiotaomicron (MIC90, 4.0 microg ml), fusobacteria (MIC90, 1.0 microg ml), peptostreptococci (MIC90, 2.0 microg ml), and clostridia, including Clostridium difficile (MIC90, 2.0 microg ml)[2]. The use of a single preoperative dose of cefminox was similar in efficacy to 3 doses of cefoxitin administered every 4 hours, and that the serum and tissue concentrations attained provide adequate antibiotic coverage[3]. Moreover, cefminox as a dual agonist of IP (Prostacyclin receptor) and PPARγ (peroxisome proliferator-activated receptor-gamma) that significantly inhibits PASMC proliferation by up-regulation of PTEN (phosphatase and tensin homolog) and cAMP ( cyclic adenosine monophosphate), suggesting that it has potential for treatment of PAH(pulmonary arterial hypertension)[4].
