Exploring Therapeutic Avenues: Applications and Mechanisms of Carbonic Anhydrase Inhibitors

Carbonic anhydrase (CA) inhibitors hold significant promise across diverse therapeutic domains owing to their multifaceted mechanism of action. This paper delves into their therapeutic applications, highlighting their potential in cystic fibrosis by normalizing bicarbonate transport, in cancer treatment by disrupting pH balance in tumor cells, and in managing renal tubular acidosis by promoting renal bicarbonate excretion. Additionally, CA inhibitors show promise in respiratory disorders, gastrointestinal disorders, cerebral edema, migraine prophylaxis, and dry eye syndrome. Mechanistically, these inhibitors interfere with the activity of CA enzymes through reversible and irreversible inhibition, modulating pH regulation and catalytic reactions. Sulfonamide inhibitors, a subclass of reversible inhibitors, particularly target the active site of CA, showing selectivity and versatility in medical applications. Ongoing research continues to explore their potential in neurological disorders, cancer, and bacterial infections. Overall, CA inhibitors present a rich landscape for therapeutic innovation, with ongoing investigations unraveling new insights into their mechanisms and applications.

碳酸酐酶（Carbonic anhydrase, CA）抑制剂因其多维度的作用机制，在众多治疗领域展现出巨大应用前景。本文探讨了该类抑制剂的治疗应用场景，着重阐明其在以下方向的应用潜力：通过恢复碳酸氢盐转运稳态改善囊性纤维化，通过干扰肿瘤细胞内pH平衡助力癌症治疗，以及通过促进肾脏碳酸氢盐排泄用于肾小管酸中毒的临床管理。此外，CA抑制剂在呼吸系统疾病、胃肠道疾病、脑水肿、偏头痛预防以及干眼症领域亦展现出应用潜力。从作用机制来看，此类抑制剂通过可逆与不可逆两种抑制方式干扰碳酸酐酶的活性，从而调控pH稳态与催化反应过程。作为可逆抑制剂子类的磺酰胺类抑制剂，可特异性结合碳酸酐酶的活性位点，在临床应用中兼具选择性与多功能性。当前仍有多项研究持续探索该类抑制剂在神经系统疾病、癌症以及细菌感染领域的应用潜力。总体而言，碳酸酐酶抑制剂为治疗创新提供了广阔的研究空间，持续开展的相关研究正不断揭示其作用机制与临床应用的全新见解。
