  Synthesis of 6-tetrazolyl-substituted sulfocoumarins acting as highly potent and selective inhibitors of the tumor-associated carbonic anhydrase isoforms IX and XII

  摘要：

  A series of 6-substituted sulfocoumarins incorporating substituted-1,2,3,4-tetrazol-5-yl moieties were synthesized by reaction of 6-iodo-sulfocoumarin and the corresponding tetrazole via the CH activation reaction. The new sulfocoumarins incorporating alkyl and substituted aryl moieties at the 1-position of the tetrazole, were investigated for the inhibition of four human (h) carbonic anhydrase (hCA, EC 4.2.1.1) isoforms, the cytosolic hCA I and II; and the transmembrane, tumor-associated hCA IX and XII. The tetrazole-substituted sulfocoumarins did not inhibit the ubiquitous, off-target cytosolic isoforms (K(I)s > 10 mu M) but showed effective inhibition against the two transmembrane CAs, with KIs ranging from 6.5 to 68.6 nM against hCA IX, and between 4.3 and 59.8 nM against hCA XII. As hCA IX and XII are validated anti-tumor targets, such prodrug, isoform-selective inhibitors as the sulfocoumarins reported here, may be useful for identifying suitable drug candidates for clinical trials.

  6-芳基取代磺基香豆素的合成及其碳酸酐酶抑制作用的研究

  摘要：

  通过使6-碘-磺基香豆素与芳基硼酸在Suzuki交叉偶联条件下反应，获得了一系列6-芳基取代的1,2-苯并x啶2,2-二氧化物。在药物化学应用，胞质hCA I和II以及药物化学应用方面，研究了在杂环6位上掺入各种取代苯基部分的新磺基香豆素类化合物对四种人（h）碳酸酐酶（CA，EC 4.2.1.1）同工型的抑制作用。跨膜，肿瘤相关的hCA IX和XII。芳基取代的磺香豆素没有抑制普遍存在的，脱靶的胞质亚型hCA I和II（K I s> 10μM），但是显示出对两个跨膜CA的有效抑制，其中K I针对hCA IX的范围为9.0至95.3 nM，针对hCA XII的范围为3.5至14.2 nM。由于hCA IX和XII是经过验证的抗肿瘤靶标，因此此类磺基香豆素，同工型选择性抑制剂可用于鉴定合适的候选药物，以用于此类药物的进一步临床试验。

  6-Substituted sulfocoumarins bearing the carboxamido, trimethylammonium as well as the cyano and methoxy moieties with interesting inhibitory activity/selectivity against the tumor associated carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA IX and XII are reported. Moieties leading to the best inhibition were tert-butylcarboxamido, phenylcarboxamido, and 4-pyridylcarboxamido, with K-I values of 2.1-8.1 nM. No inhibition of the off-target hCA II and I was observed. A number of these compounds were evaluated against HT-29 colon cancer cell lines ex vivo. Compounds 9c and 9e revealed effective cytotoxic effects after 72 h of incubation in both normoxic and hypoxic conditions, unlike sulfonamide CA inhibitors that show such effects only in hypoxia. These results may be of particular importance for the choice of future drug candidates targeting hypoxic tumors and metastases, considering the fact that a sulfonamide CA IX inhibitor (SLC-0111) is presently in phase I clinical trials.
