syndrome—coronavirus 2 (SARS‐CoV‐2) has impacted the quality of life and cost hundreds‐of‐thousands of lives worldwide. Based on its global spread and mortality, there is an urgent need for novel treatments which can combat this disease. To date, the 3‐chymotrypsin‐like protease (3CLpro), which is also known as the mainprotease, is considered among the most important pharmacological targets. The vast majority
自爆发以来,严重急性呼吸系统综合症冠状病毒 2 (SARS-CoV-2) 影响了生活质量,并导致全世界数十万人丧生。鉴于其在全球的传播和死亡率,迫切需要能够对抗这种疾病的新疗法。迄今为止,3-胰凝乳蛋白酶样蛋白酶(3CL pro )也被称为主要蛋白酶,被认为是最重要的药理学靶点之一。绝大多数研究的 3CL前体抑制剂都是有机非共价结合剂。在此,建议使用无机配位共价结合剂来减弱蛋白酶的活性。 Re 三羰基复合物被鉴定为 3CL pro的协调共价酶抑制。初步研究表明 3CL pro对几种人类蛋白酶具有选择性抑制作用。这项研究首次展示了金属配合物作为 3CL半胱氨酸蛋白酶抑制剂的例子。
Core-modified phthalocyanine analogues with a seven-membered ring unit in place of a five-membered ring unit
analogues with a seven-memberedring unit in place of a five-membered ring unit were synthesized from aromatic dicarbonitriles bearing cyano groups at 1,4-separate positions. Based on the spectroscopic analyses and theoretical calculations, tetraazachlorine-like electronic structures of these novel compounds stemming from severe twist of the conjugation system at the seven-memberedring unit have been
