Coclaurine
0 ImagesCoclaurine is a class of tetrahydroisoquinoline alkaloids that can be isolated from Sarcopetalum harveyanum with anticancer activity. Coclaurine is a nicotinic acetylcholine receptor (nAChRs) antagonist. Coclaurine is a key molecule in S. tetrandra responsible for EFHD2 inhibition. Coclaurine can downregulate EFHD2-related NOX4-ABCC1 signaling and enhanced Cisplatin (HY-17394) sensitivity. Coclaurine suppresses the stemness and metastatic properties of NSCLC cells. Coclaurine disrupts the interaction between the transcription factor FOXG1 and the EFHD2 promoter, leading to a reduction in EFHD2 transcription.

Asoxime dichloride
0 ImagesSynonyms: HI-6Asoxime dichloride (HI-6) is an orally active thiosemicarbazone-based antidote. Asoxime dichloride is a reversible inhibitor of AChE, and its core mechanism of action is to re-activate AChE inhibited by nerve toxins, thereby restoring the cholinergic nerve function. Asoxime dichloride significantly restores the function of poisoned muscles without reactivating AChE. Asoxime dichloride is an antagonist of acetylcholine receptors (AChRs), including nicotinic receptor and α7 nAChR.
