The natural product harmine, a representative β-carboline alkaloid from the seeds of Peganum harmala L. (Zygophyllaceae), possesses a broad spectrum of biol. activities. In this study, a novel series of harmine derivatives containing N-benzylpiperidine moiety were identified for the treatment of Alzheimer’s disease (AD). The results showed that all the derivatives possessed significant anti-acetylcholinesterase (AChE) activity and good selectivity over butyrylcholinesterase (BChE). In particular, compound ZLWH-23 exhibited potent anti-AChE activity (IC50 = 0.27μM) and selective BChE inhibition (IC50 = 20.82μM), as well as acceptable glycogen synthase kinase-3 (GSK-3β) inhibition (IC50 = 6.78μM). Mol. docking studies and mol. dynamics simulations indicated that ZLWH-23 could form stable interaction with AChE and GSK-3β. Gratifyingly, ZLWH-23 exhibited good selectivity for GSK-3β over multi-kinases and very low cytotoxicity towards SH-SY5Y, HEK-293T, HL-7702, and HepG2 cell lines. Importantly, ZLWH-23 displayed efficient reduction against tau hyperphosphorylation on Ser-396 site in Tau (P301L) 293T cell model. Collectively, harmine-based derivatives could be considered as possible drug leads for the development of AD therapies.
402-49-3, 4-Trifluoromethylbenzyl bromide is a useful research compound. Its molecular formula is C8H6BrF3 and its molecular weight is 239.03 g/mol. The purity is usually 95%.
4-Trifluoromethylbenzyl bromide is a choline derivative that acts as an anticancer agent. It is structurally similar to the anticancer drug doxorubicin, which has been shown to be effective against breast cancer and leukemia. 4-Trifluoromethylbenzyl bromide interacts with cellular proteins, including choline kinase, and inhibits the mitochondrial pathway. This leads to cell death through apoptosis. The molecule also interacts with nucleotide bases such as thymine and cytosine in DNA, inhibiting transcription and replication. 4-Trifluoromethylbenzyl bromide binds strongly to the hydroxyl group of cholesterol by an electrophilic substitution mechanism to form a covalent bond with its hydroxy group. The molecule can also bind to chloride ions by an ionic bond., Reference of 402-49-3
