Protein kinase Cβ (PKCβ) is considered as an attractive molecular target for the treatment of COVID-19-related acute respiratory distress syndrome (ARDS). Several classes of inhibitors have been already identified. In this article, we developed and validated ligand-based PKCβ pharmacophore models based on the chemical structures of the known inhibitors. The most accurate pharmacophore model, which correctly predicted more than 70% active compounds of test set, included three aromatic pharmacophore features without vectors, one hydrogen bond acceptor pharmacophore feature, one hydrophobic pharmacophore feature and 158 excluded volumes. This pharmacophore model was used for virtual screening of compound collection in order to identify novel potent PKCβ inhibitors. Also, molecular docking of compound collection was performed and 28 compounds which were selected simultaneously by two approaches as top-scored were proposed for further biological research.

蛋白激酶Cβ(PKCβ)被认为是治疗新型冠状病毒肺炎相关急性呼吸窘迫综合征(ARDS)的一个有吸引力的分子靶点。已经鉴定出几类抑制剂。在本文中,我们基于已知抑制剂的化学结构开发并验证了基于配体的PKCβ药效团模型。最准确的药效团模型正确预测了测试集中70%以上的活性化合物,该模型包括三个无向量的芳香药效团特征、一个氢键受体药效团特征、一个疏水药效团特征和158个排除体积。该药效团模型用于化合物库的虚拟筛选,以鉴定新型强效PKCβ抑制剂。此外,还对化合物库进行了分子对接,并提出了28种通过两种方法同时被选为高分的化合物用于进一步的生物学研究。
