Synthesis of positional isomers is a commonly used technique in drug design. Accordingly, based on prior SAR studies of 3'R,4'R-di-O-(S)-camphanoyl-(+)-cis-khellactone (DCK, 1) analogues, a series of mono- and disubstituted chromone derivatives of 3'R,4'R-di-O-(-)-camphanoyl-2',2'-dimethyldihydropyrano[2,3-f]chromone (DCP, 4) were designed and synthesized. Together with 1 and 4-methyl DCK (2), all
位置异构体的合成是药物设计中常用的技术。因此,根据先前对3'R,4'R-di-O-(S)-樟脑酰基-(+)-顺式-甲壳酮(DCK,1)类似物的SAR研究,一系列的单或双取代色酮衍生物设计并合成了3'R,4'R-di-O-(-)-樟脑酰基-2',2'-二甲基二氢吡喃并[2,3-f]色酮(DCP,4)。连同1和4-甲基DCK(2)一起,对所有新合成的DCP类似物(4-21)筛选针对H9淋巴细胞中的非耐药菌株和多重逆转录酶(RT)的抗HIV-1活性。 MT4细胞系中具有抗抑制剂作用的菌株。几种DCP类似物(4、5、7、8、13和17)在非耐药菌株测定中显示出极高的抗HIV活性,EC(50)值在0.00032至0之间。0057 microM和显着的治疗指数(TI)从5.6 x 10(3)到1.16 x 10(5),与2的相似(EC(50)0.0059 microM,TI> 6.6 x 10(3))和优于1(EC(50)0
