카르무스틴 C화학적 특성, 용도, 생산
개요
Carmustine is a nitrogen mustard β-chloro-nitrosourea compound that is used as an alkylating agent. It forms interstrand crosslinks in DNA, which prevents DNA replication and transcription leading to apoptosis. Carmustine is also reported to inhibit glutathione reductase, thioredoxin reductase, and lipoamide dehydrogenase. Carmustine has been tested in clinical trials as a cytostatic agent for Hodgkin’s and non-Hodgkin’s lymphoma, myeloma, malignant melanoma, glioblastoma, and other brain tumors.
화학적 성질
Carmustine is an orange-yellow crystalline
solid or powder.

잠재적 노출
BCNU has been used since 1971 as an
antineoplastic agent in the treatment of Hodgkin’slymphoma; multiple meyloma; and primary or metastatic
brain tumors. It also has been reported to have antiviral,
antibacterial, and antifungal activity, but no evidence was
found that it is used in these ways. BCNU is not known to
be naturally occurring. Health professionals who handle
this drug (for example, pharmacists, nurses, and physicians)
may possibly be exposed to BCNU during drug preparation, administration, or cleanup; however, the risks can be
avoided through use of containment equipment and proper
work practices
Carcinogenicity
Bis(chloroethyl) nitrosourea (BCNU) is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
환경귀착
It is generally assumed that BCNU exerts its cytotoxicity
through the liberation of alkylating and carbamoylating
moieties. An alkylating entity, particularly chloroethyl carbonium
ion, is strongly electrophilic and can alkylate a variety
of biomolecules, including the purine and pyrimidine bases of
DNA. BCNU causes DNA interstrand cross-linking, which is
associated with cytotoxicity. The carbamoylation of lysine
residues of protein can inactivate certain enzymes, thus interfering
with DNA and RNA synthesis and repair processes. The
inhibition of glutathione reductase by this carbamoylation
further contributes to cytotoxicity.

cause rapid decomposition. Most stable at pH 4 in aqueous
solution or petroleum ether.
폐기물 처리
It is inappropriate and possibly dangerous to the environment to dispose of expired or
waste pharmaceuticals by flushing them down the toilet or
discarding them to the trash. Household quantities of
expired or waste pharmaceuticals may be mixed with wet
cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If
possible return the pharmaceutical to the manufacturer for
proper disposal being careful to properly label and securely
package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a
state licensed medical waste contractor to dispose by burial
in a licensed hazardous or toxic waste landfill or
incinerator.
