ํŠน์ง•
A more specific and potent anti-medulloblastoma agent compared to Vincristine.
์‹œํ—˜๊ด€ ๋‚ด(In vitro)
Lomustine inhibits the growth of ZR-75-1 and U373 with IC50 of 12 ฮผM and 15 ฮผM, respectively. This compound reduces the level of expression of the DNA repair protein O6-alkylguanine-DNA alkyltransferase. It (420 ฮผM) triggers apoptosis through the mitochondrial pathway via decrease in the level of the anti-apoptosis proteins Bcl-2 and Bcl-xl, respectively, in both medulloblastoma and normal human epithelial and fibroblast cells. This chemical induces cell cycle delay in G2/M phase in medulloblastoma cells and up-regulates p21 protein level in a p53-independent manner in HFSN1 cells.
์ƒ์ฒด ๋‚ด(In vivo)
Lomustine can cause delayed, cumulative dose-related, chronic hepatotoxicity that is irreversible and can be fatal. This compound could result in infrequent severe hematological toxicity in cats with spontaneously arising tumors, and the incidence of either grade III or IV neutropenia and thrombocytopenia is 4.1% and 1.0%, respectively. It trends toward a greater likelihood for progressive neutropenia and statistically significant higher response rates in cats with spontaneously arising tumors.
