Biosynthesisofneurotransmitters
Neurotransmitters are signaling molecules used by neurons to communicate across chemical synapses. The receptors for neurotransmitters include G-protein coupled receptors (GPCRs) and ligand-gated ion channels. The biogenic amines are neurotransmitters derived from amino acids, and include dopamine, epinephrine, GABA, histamine and serotonin. For each of these, decarboxylation of an amino acid is a key step. GABA, gam......阅读全文

新冠靶点新视角五靶向宿主的抗病毒药物靶点DHODH
近期，武汉大学生科院和华东理工大学药学院合作研究发现，二氢乳酸脱氢酶（DHODH）的新型有效抑制剂针对RNA病毒具有广谱抗病毒感染的特点。 目前开发广谱抗病毒药物（BSA）主要有两种策略，一是利用核苷或核苷酸类似物，二是靶向宿主的抗病毒制剂（HTA）。核苷或核苷类似物通常会引起耐药性和毒性，但由于病
