“…[27] In our previous work, we explored the coumarin linked with various active moieties like sulfonamides and oxime ethers through piperazine, of which compounds VIII and IX showed good inhibition against hCA IX and hCA XII with K i of 4.1 and 9.4 µM, respectively. [28] Analyzing the above literature, which indicated that the prodrug approach of coumarin and its derivatives designed to achieve a potent and selective inhibition against hCA IX and hCA XII is reported to have the 6 th and 7 th positions as the most favorable for substitutions as shown in structure I-VII whereas the substitutions at the 3 rd and 4 th positions coumarin ring from our previous work showed moderately active inhibition against cancer-associated isoforms hCA IX and hCA XII. In this work, we designed the new series of coumarin derivatives by moving the substitutions to the 6 th F I G U R E 1 Coumarin derivatives as selective human carbonic anhydrase (hCA) IX and hCA XII inhibitors.…”

Carbonic anhydrase isoforms IX and XII are overexpressed in hypoxic tumor cells regulating various physiological processes such as cell proliferation, invasion, and metastasis, resulting in the onset and spread of cancer. Selective inhibition of these enzymes is a promising strategy for anticancer therapy. Coumarin derivatives were identified as selective and potent inhibitors of these isoforms. This study reports 6‐aminocoumarin sulfonamide and oxime ether derivatives linked through a chloroacetyl moiety tethered to piperazine and piperidone, respectively, showing selective inhibition against human carbonic anhydrase (hCA) IX and XII with Ki ranging from 0.51 to 1.18 µM and 0.89–4.43 µM. While the sulfonamide derivative 8a exhibited submicromolar inhibition against hCA IX and XII with Ki 0.89 and 0.51 µM, the oxime ether derivatives showed lower activity than the sulfonamides, with the compound 5n inhibiting hCA IX and hCA XII with a Ki of 1.055 and 0.70 µM, respectively. The above results demonstrate the potential of these derivatives as selective, potent inhibitors of carbonic anhydrase IX and XII and provide a foundation for further optimization and development as effective anticancer agents. Further, the binding mode of the synthesized derivatives in the active site were examined using molecular docking and dynamic simulation studies.

“…Over the past years, researchers have leveraged this privileged scaffold to design inhibitors incorporating diverse "tails," with the intention of identifying lead molecules, particularly for isoforms hCA IX and XII. [29][30][31][32][33] Numerous research groups have contributed to this endeavor, producing a significant body of literature demonstrating the efficacy and selectivity of these designed compounds in inhibiting these tumor-associated isoforms (hCA IX and/or XII) while differentiating them from the prevalent, cytosolic, and main offtarget isoforms, namely hCA I and II. [29][30][31][32][33] This approach not only underscores the potential of coumarin-based derivatives for targeted inhibition but also highlights their utility in addressing the challenge of isoform selectivity, a critical consideration in drug development.…”

This study introduces a series of ten hybrid molecules DK(1‐10), which combine diazo and coumarin moieties along with diverse aromatic substitutions. The primary objective was to evaluate the inhibitory capabilities of these compounds against four prominent isoforms: the cytosolic hCA I and II, as well as the tumor‐associated membrane‐bound hCA IX and XII. Impressively, the majority of the tested compounds exhibited significant inhibition activity against the tumor‐associated isoforms hCA IX and XII, with KI values ranging from 29.2 to 293.3 nM. Notably, compound DK‐8 displayed particularly robust inhibitory activity against the tumor‐associated membrane‐bound isoforms, hCA IX and XII, yielding KI values of 32.5 and 29.2 nM, respectively. Additionally, another derivative, DK‐9, containing a primary sulfonamide, exhibited notable inhibition against hCA XII with a KI value of 36.4 nM. This investigation aimed to explore the structure‐activity relationships within these compounds, shedding light on how various substitutions and structural components influence their inhibitory potential. As a result, these compounds present promising candidates for further exploration in medicinal and pharmacological research. Their ability to selectively inhibit specific isoforms, particularly those associated with hypoxic tumors, suggests their potential as foundational compounds for the development of novel therapeutic agents.

Carbonic anhydrases (CAs) are crucial in regulating various physiological processes in the body. The overexpression of isoforms human carbonic anhydrases (hCA) IX and hCA XII is linked to tumour progression. The selective inhibition of CA IX and CA XII isoforms can result in the development of better cancer treatment strategies. The tail approach based on coumarin derivatives was known for selective inhibition of isoforms IX and XII. This study explores the potential of coumarin derivatives (7a–k, 8a–s and 9a–g) as selective hCA IX and hCA XII inhibitors. The synthesised derivatives exhibited potent and selective inhibition towards hCA IX and XII, with Ki values in the range of 0.58‒3.33 µM and 0.48‒2.59 µM, respectively. The oxime ether derivative 7d was found to be the most potent one against hCA IX, with a Ki value of 0.58 µM, and phenyl hydrazine derivative 8a, with a Ki value of 0.48 µM against hCA XII, was the most potent one among the synthesised molecules. The potent isoform‐specific carbonic anhydrase IX and XII inhibition suggests that 7d and 8a can be taken further towards the development of potent anticancer agents.
