Tinea capitis is local alopecia caused by a dermatophyte infection of the scalp. produces the squalene epoxidase enzyme, which has a crucial role in prolonged dermatophyte infection, as well as in synthesizing fatty acids in this dermatophyte group. This study analyzes compounds as anti-alopecia by inhibiting the squalene epoxidase enzyme formation, . The structure of compounds was prepared using the MolView Web application. The compound docked to squalene epoxidase using AutoDock Vina in PyRx 0.8, followed by PyMOL for visualization, and the Proteins Plus program to analyze the complexity. The binding affinity value of catechin, epicatechin (-8.0 kcal/mol), and anthocyanin (-7.8 kcal/mol) compounds was higher than the positive control (terbinafine, -6.7 kcal/mol). Pre-ADMET demonstrated that catechin and epicatechin had moderate Human Intestinal Absorption (66.71%), but anthocyanin was very good (100%). Caco-2 parameters for catechin and epicatechin were relatively low (<4 nm s ), while anthocyanin, theobromine, and terbinafine were within 4-70 nm s . Plasma protein binding shows catechin, epicatechin, and anthocyanin diffuse through the plasma membrane and interact with plasma proteins. The toxicity results for all compounds are mutagenic, and only terbinafine is carcinogenic. Based on the Lipinski's "Rule of Five," compounds from can be given orally. Catechin and epicatechin compounds have the potential to act as anti-alopecia. These two compounds can diffuse and interact with plasma proteins so they are directly on the target when given orally.
头癣是由头皮皮肤癣菌感染引起的局部脱发。皮肤癣菌产生角鲨烯环氧酶,该酶在皮肤癣菌的长期感染以及该皮肤癣菌群脂肪酸的合成中起关键作用。本研究通过抑制角鲨烯环氧酶的形成来分析化合物作为抗脱发剂的作用。使用MolView网络应用程序制备化合物的结构。在PyRx 0.8中使用AutoDock Vina将化合物对接至角鲨烯环氧酶,随后使用PyMOL进行可视化,并使用Proteins Plus程序分析其复杂性。儿茶素、表儿茶素(-8.0千卡/摩尔)和花青素(-7.8千卡/摩尔)化合物的结合亲和力值高于阳性对照(特比萘芬,-6.7千卡/摩尔)。ADMET预预测表明,儿茶素和表儿茶素具有中等的人体肠道吸收(66.71%),但花青素的吸收非常好(100%)。儿茶素和表儿茶素的Caco-2参数相对较低(<4纳米/秒),而花青素、可可碱和特比萘芬的参数在4-70纳米/秒之间。血浆蛋白结合显示儿茶素、表儿茶素和花青素可穿过质膜并与血浆蛋白相互作用。所有化合物的毒性结果均具有致突变性,只有特比萘芬具有致癌性。根据Lipinski的“五规则”,来自[具体来源未提及]的化合物可以口服。儿茶素和表儿茶素化合物具有作为抗脱发剂的潜力。这两种化合物可以扩散并与血浆蛋白相互作用,因此口服时它们直接作用于靶点。
