by the mercury-catalyzed condensation procedure. CDA activity varies significantly with the ring size of the urea aglycon the reaches its maximum level for the seven-membered analogues 16 and 17. The unexpected high potency of nucleoside 17 (Ki = 2.5 X 10(-8) M, human liver enzyme) is reported. This compound represents the most potent inhibitor of human liver CDA yet discovered.
合成了五种β-D-呋喃呋喃糖基环状脲核苷(14-18),其环大小为五至八元,并被评估为胞苷脱氨酶(CDA)抑制剂。在含有仅提供β-端基异构体的HgO / HgBr2混合物的比催化活性下,通过缩合反应利用前体保护的核苷(9-13),该缩合反应是利用硅烷化的脲与卤代糖。已知的1-(2,3,5-三-O-苯甲酰基-β-呋喃呋喃糖基)-1,2-二氢嘧啶-2-酮(19)的催化加氢提供与通过汞催化的缩合步骤获得的核苷10相同。CDA活性随尿素糖苷配基的环大小变化而显着变化,达到七元类似物16和17的最大水平。核苷17的意想不到的高效能(Ki = 2.5 X 10(-8)M,人肝酶)的报道。该化合物代表尚未发现的最有效的人类肝脏CDA抑制剂。

Seven-membered heterocyclic nucleosides used to inhibit the deamination enzyme responsible for the inactivation of arabinosylcytosine (ara--C). Preferred nucleosides containing a seven-member aglycone are as follows: ##STR1## Preferred aglycones are as follows: ##STR2## Active components utilized against pyrimidine deaminases from mammalian tissues (mouse kidney and human liver) showed optimum advantage when compared with tetrahydrouridine (THU).

to complement existing antiviral and anticancer therapies and prevent the emergence of drug resistance, thus making such therapies effective for longer periods of time. Here, we synthesised nucleosides containing seven-membered nucleobases based on azepinone and compared their inhibitory potential against human cytidine deaminase (hCDA) and APOBEC3A with previously described 2′-deoxyzebularine (dZ)
APOBEC3 (APOBEC3A-H) 酶家族是人类先天免疫系统的一部分,可将单链 DNA (ssDNA) 中的胞嘧啶脱氨基为尿嘧啶,从而防止致病性遗传信息的传播。然而,APOBEC3 诱导的突变会促进病毒和癌症的进化,从而导致疾病的进展和耐药性的发展。因此,APOBEC3抑制提供了补充现有抗病毒和抗癌疗法并防止耐药性出现的可能性,从而使此类疗法的有效性更长。在这里,我们合成了含有基于 azepinone 的七元核碱基的核苷,并将其对人胞苷脱氨酶 (hCDA) 和 APOBEC3A 的抑制潜力与先前描述的 2'-deoxyzebularine (dZ) 和 5-氟-2'-deoxyzebularine (FdZ) 进行了比较。野生型 APOBEC3A 的纳摩尔抑制剂是通过在 DNA 发夹的 TTC 环中掺入 1,3,4,7-四氢-2 H -1,3-diazepin-2-one 代替靶标 2'获得的-脱氧胞苷提供的K
