ERβ Ligands. Part 2: Synthesis and structure–activity relationships of a series of 4-hydroxy-biphenyl-carbaldehyde oxime derivatives
摘要:
A series of biphenyl carbaldehyde oximes (6) was prepared and shown to have significant selectivity for the estrogen receptor-beta (ERbeta). The exploitation of the oxime moiety as a hydrogen bond donating group, which mimicked the C-ring of genistein makes these compounds unique. Molecular modeling studies showed the oxime moiety hydrogen bonding to the histidine residue, which was supported by the structure-activity relationships. The most potent compounds in this study had IC50 values in a radio-liaand binding assay of between 8-35 nM. Among the most selective compounds were 6i and 6s (49- and 31-fold ERbeta selective, respectively). (C) 2004 Elsevier Ltd. All rights reserved.

Humanimmunodeficiency virus (HIV) reversetranscriptase (RT) associated ribonuclease H (RNase H) remains the only virally encoded enzymatic function not targeted by current drugs. Although a few chemotypes have been reported to inhibit HIV RNase H in biochemical assays, their general lack of significant antiviral activity in cell culture necessitates continued efforts in identifying highly potent
人类免疫缺陷病毒(HIV)逆转录酶(RT)相关的核糖核酸酶H(RNase H)仍然是当前药物未靶向的唯一病毒编码的酶功能。尽管在生化分析中已经报道了一些化学型抑制HIV RNase H,但是它们在细胞培养中普遍缺乏显着的抗病毒活性,因此需要继续努力鉴定具有高效抗病毒活性的RNase H抑制剂。我们在此报告了3-羟基嘧啶-2,4-二酮(HPD)化学型的新6-芳硫基亚型的设计,合成,生化和抗病毒评估。在生化分析中,这些新的类似物在单个纳摩尔范围内抑制RT RNase H,而在浓度高达10μM的情况下却不抑制RT聚合酶(pol),具有非凡的生化抑制选择性。许多类似物还在低至亚微摩尔范围内抑制整合酶链转移(INST)活性。更重要的是,大多数类似物都在低微摩尔范围内抑制HIV而无细胞毒性。最后,复合13j(RNase H IC 50 = 0.005μM; RT pol IC 50 = 10μM;

isoquinoline-1,3-dione as a viable chemotype for selectivelyinhibiting TDP2. The initial hit compound 43 was identified by screening our in-house collection of synthetic compounds. Further structure–activity relationship (SAR) studies identified numerous analogues inhibiting TDP2 in low micromolar range without appreciable inhibition against the homologous TDP1 at the highest testing concentration
