  Interaction of cycloSal-Pronucleotides with Cholinesterases from Different Origins. A Structure−Activity Relationship

  摘要：

  A large number of cycloSal-nucleotide triesters 1-49 have been studied concerning their ability to inhibit cholinesterases of different origins as well as to inhibit HIV replication in cell culture. It was shown that none of the triesters showed inhibitory effects against human acetylcholinesterase (AChE; isolated enzyme) as well as against AChE from beef erythrocytes and calf serum. In contrast, inhibition of butyrylcholinesterase (BChE) has been observed for some triesters in human and mouse serum. cycloSal pronucleotides showed strong competitive inhibition with respect to the substrate acetylcholine chloride (K-i/K-m: similar to2 x 10(-5)) and acted by time-dependent irreversible inhibition of the human serum BChE. Detailed studies demonstrated that the inhibitory effect against BChE is dependent on the nucleoside analogue, the substitution pattern of the cycloSal-moiety, and particularly on the stereochemistry at the phosphorus atom. Structural requirements to avoid the inhibition of BChE by cycloSal-nucleotide triesters have been elucidated in the reported study.

  Cyclo-saligenyl-5-fluoro-2′-deoxyuridinemonophosphate (cycloSal-FdUMP) — A New Prodrug Approach for FdUMP

  摘要：

  The synthesis of cycloSal-FdUMP 3a-d as a new prodrug approach for FdU 1 is described. Phosphotriesters 3 release the FdUMP 2 selectively by a controlled, chemically induced tandem reaction in hydrolysis studies. The biological activity (IC50) of cycloSal-phosphotriesters 3 was evaluated in FM3A/O cells and FM3A/TK- cells.

In hydrolysis studies, 9 and 10 decomposed under mild aqueous basic conditions releasing solely ddAMP (7) and d4AMP (8), as well as the diols 14. Further hydrolysis studies under acidic conditions showed a marked increase in stability with respect to the acid-catalyzed cleavage of the glycosyl bond.

  prototype compounds and particularly triesters 2c,d exhibited pronounced anti-EBV activity making these compounds promising candidates for further development. However, the 3'-ester derivatives were devoid of any antiviral activity while the 3'-aminoacyl derivatives showed an antiviral activity dependent upon the amino acid and the Calpha-configuration

  关于其潜在的抗EBV活性，研究了新型cycloSal-BVDUMP三酯2-4 5-[（（E）-2-溴乙烯基）-2'-脱氧尿苷（BVDU，1）。除了3'-未修饰的cycloSal-BVDUMP三酯2a-f外，3'-羟基官能团还被不同的脂肪族羧酸（3a-g）和具有天然和非天然Calpha-构型（4a- m）。除了这些化合物的合成以外，还将报道新衍生物的不同物理化学性质，即亲脂性和水解行为。可以证明，通过在pH 6.8和7.3的磷酸盐缓冲液以及P3HR-1细胞提取物中进行化学水解，可以从大多数化合物中释放出单磷酸盐BVDUMP而不是3'，5'-环状BVDUMP。最后，测试了新化合物的抗EBV活性。结果，原型化合物，特别是三酯2c，显示出明显的抗EBV活性，使这些化合物有望成为进一步开发的候选物。但是，3'-酯衍生物没有任何抗病毒活性，而3'-氨基酰基衍生物显示出取决于氨基酸和Calpha-构型的抗病毒活性。

This pro-nucleotide concept has been designed to deliver d4TMP (2) by selective chemical hydrolysis.
