approach for thymidine monophosphate (TMP) in bacterial cells, we have synthesized a series of conjugates of TMP with biotin having an oxymethyleneoxy ester, a carboxy ester, and different carboxamide linkers between the carboxyl group of biotin and the 3′-OH group of TMP. The synthetic strategy starts from 5′-O-(dibenzylphosphate)-thymidine having the linkers already connected at the 3′-position. Likewise
为寻找细菌细胞中胸苷单磷酸(TMP)的递送方法,我们合成了一系列TMP与生物素结合物,该结合物在生物素的羧基和3'之间具有羟甲基氧酸酯,羧基酯和不同的羧酰胺连接基。 TMP的-OH基。合成策略从具有在3'-位已经连接的接头的5'- O-(磷酸二苄基酯)-胸苷开始。同样,卡那霉素A使用氨基甲酰基或硫代乙基氨基甲酰基在TMP的3'-位连接。这些缀合物均不能维持ΔthyA,ΔphoA大肠杆菌菌株的生长。
