The antitumor agent N,N'-bis(2-chloroethyl)-N-nitrosourea (BCNU) is known to be unstable in aqueous solution, and to degrade spontaneously to reactive alkylating and carbamoylating intermediates. Whereas the alkylating component is believed to be responsible for the antitumor effects of this drug, it

Placental biotransformation reactions may modulate the effect a xenobiotic has on the developing fetus. However, in spite of the critical role the placenta plays in supporting fetal life, little is known about the pharmacology and toxicology of the human placenta.

The cDNA of a protein kinase C-regulated chloride channel (CIC-3) was cloned. CIC-3 encodes 760 amino acids, which has significant amino acid identity with the previously cloned CIC chloride channels. CIC-3 cRNA elicited the chloride currents in Xenopus oocytes, which

It has been reported that the toxicity of carmustine (BCNU)/cyclophosphamide (CY)/etoposide regimen (when BCNU is split into 4 doses) is less than that of BCNU/CY/cisplatin regimen (when the same amount of BCNU is administered as a single dose). We hypothesized

The protein A24 content of Ehrlich ascites tumor cells increased several-fold following treatment of cell cultures with nitrosoureas, but did not increase when other alkylating agents not containing carbamoyl moieties were tested. The same nitrosoureas and, in addition, 2-chloroethyl isocyanate
