Methods are provided for identifying anti-HIV therapeutic compounds substituted with carboxyl ester or phosphonate ester groups. Libraries of such compounds are screened optionally using the novel enzyme GS-7340 Ester Hydrolase. Compositions and methods relating to GS-7340 Ester Hydrolase also are provided.
chiral precursor for the synthesis of the side chain pharmacophore of cholesterol-lowering drug atorvastatin. Herein, a robust carbonyl reductase (LbCR) was newly identified from Lactobacillus brevis, which displays high activity and excellent diastereoselectivity toward bulky t-butyl 6-cyano-(5R)-hydroxy-3-oxo-hexanoate (7). The engineered Escherichiacoli cells harboring LbCR and glucose dehydrogenase
叔丁基-6-氰基-(3 R,5 R)-二羟基己酸酯是一种先进的手性前体,用于合成降胆固醇药物阿托伐他汀的侧链药效团。在本文中,从短乳杆菌中新鉴定出一种强健的羰基还原酶(Lb CR),它对高密度的叔丁基6-氰基-(5 R)-羟基-3-氧代己酸叔丁酯具有很高的活性和非对映选择性(7)。具有Lb CR和葡萄糖脱氢酶(用于辅因子再生)的工程化大肠杆菌细胞被用作生物催化剂,用于不对称还原底物7。结果,多达300 g L –1的水不溶性底物以351 g L –1 d –1的时空产率被完全转化为相应的手性二元醇,de > 99.5%de,表明了巨大的潜力的Lb的CR对非常笨重和实际合成双向的畅销他汀类药物-手性3,5-二羟基羧酸侧链。

ketones have been synthesized by the reduction of the corresponding ketones with a keto ester reductase isolated from bakers’ yeast (YKER-I). The reduction of α-keto esters affords the corresponding (S)- or (R)-hydroxy esters selectively, where the stereochemical course depends on the chain length of the alkyl substituent on the carbonyl group. An α-keto short alkanoic ester affords the corresponding
