Four new series of aromatic sulfamates were synthesized and investigated for the inhibition of four human (h) isoforms of zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), hCA I, II, IX, and XII. The reported derivatives, obtained by a sulfamoylation reaction of the corresponding phenolic precursors, bear 3,5-diarylpyrazoline moieties as spacers between the benzenesulfamate fragment which binds the
合成了四个新系列的芳族氨基磺酸盐,并研究了它们对锌酶碳酸酐酶(CA,EC 4.2.1.1),hCA I,II,IX和XII的四种人(h)同工型的抑制作用。通过相应的酚类前体的氨磺酰化反应获得的已报道的衍生物带有3,5-二芳基吡唑啉部分,作为结合来自活性位点的锌离子的苯氨基磺酸盐片段和抑制剂尾巴之间的间隔基。吡唑啉是具有生物学优势的支架,具有多种生物活性,例如抗增殖作用。测试了这些衍生物对胞质,hCA I和II(脱靶同种型)和跨膜,与肿瘤相关的hCA IX和XII酶(抗癌靶标)的抑制作用。通常,hCA I不能被有效抑制,而许多低纳摩尔抑制剂被证明可抵抗hCA II(KIs在0.42-90.1 nM范围内),IX(KIs在0.72-63.6 nM范围内)和XII(KIs在0.88-85.2 nM范围内)。对于CA II,吡唑啉环上的最佳取代片段包括3-芳基上的4-氨基磺酸基和5-芳基上的卤素或
