•Developmental toxicity and neurotoxicity of matrine and sophocarpine were examined.•Both drugs induced teratogenic and lethal effects to zebrafish embryos.•They significantly altered spontaneous movement and inhibited swimming behavior.•The low EC50 for swimming behavior indicate a neurotoxic potential of both drugs.
Matrine and sophocarpine are two major matrine-type alkaloids included in the traditional Chinese medicine (TCM) Kushen (the root of Sophora flavescens Ait.). They have been widely used clinically in China, however with few reports concerning their potential toxicities. This study investigated the developmental toxicity and neurotoxicity of matrine and sophocarpine on zebrafish embryos/larvae from 0 to 96/120 h post fertilization (hpf). Both drugs displayed teratogenic and lethal effects with the EC50 and LC50 values at 145 and 240 mg/L for matrine and 87.1 and 166 mg/L for sophocarpine, respectively. Exposure of matrine and sophocarpine significantly altered spontaneous movement and inhibited swimming performance at concentrations below those causing lethality and malformations, indicating a neurotoxic potential of both drugs. The results are in agreement with most mammalian studies and clinical observations.
