      Lomustine (CCNU) is an alkylating nitrosourea compound used in chemotherapy. ;IC50 Value:;In vitro: vincristine and lomustine trigger apoptosis in all these cells through the mitochondrial pathway via decrease in the level of the anti-apoptosis proteins Bcl-2 and Bcl-xl, respectively [1]. There was significant correlation between the level of cadherin-associated protein beta 1 (CTNNB1) and Aurora kinase A (STK15) proteins and neurotrophic tyrosine kinase receptor type 3 (TRKC) mRNA and the proportion of apoptosis induced by vincristine, the combination of both drugs, and lomustine, respectively [4].;In vivo: IC50 values for CCNU admixed and encapsulated with lipid vesicles were 18+/-4.9 and 14.0+/-2.2 microM, respectively, compared to 83+/-11.0 microM for free CCNU in rats [2]. Eight of the 19 dogs (42%) had a measurable response to CCNU. One dog had a durable complete response for 440 days. Seven dogs (37%) had a partial response for a median and mean duration of 77 days and 109 d MedChem Express HY-13669
