产品介绍
Melittin TFA(20449-79-0(free base)) 是一种含有 26 个氨基酸残基的小蛋白质,是蜂毒的主要毒性成分。它是一种 PLA2 活化剂,可刺激低分子量 PLA2 的活性,而不会增加高分子量 PLA2 的活性。

产品描述

Melittin TFA is a small protein containing 26 amino acid residues, is the principal toxic component of bee venom. Melittin is a PLA2 activator, stimulates the activity of the low molecular weight PLA2, while it does not the increase activity of the high molecular weight PLA2.

体外活性

Melittin, an immunologically related PLA2 stimulating peptide from bee venom, increases the activity of the high molecular weight enzyme[1]. Melittin is a cytotoxic peptide from bee venom. Melittin exhibits toxicity against both A2780CR and A2780 cells, with IC50 values of 4.5 and 6.8 μg/mL, respectively. Melittin has natural anti-bacterial, anti-viral, and anti-inflammatory properties. It has also been shown to have diverse anticancer effects in several different cancer cell lines including those of gastric, breast, ovarian, liver, prostate, cervical, and lung origins. The mechanisms by which Melittin, an amphipathic haemolytic peptide, exerts its potential anticancer effects include inhibition of cell proliferation, induction of apoptosis, and direct necrosis. Melittin can also prevent EGF-induced cell invasion through its inhibition of the PI3K/Akt/mTOR signaling pathway, but this is primarily related to breast cancer cells[2].
