Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts. among the adducts, o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties, which can eventually lead to chromosomal aberrations, point mutations, and cell death. this lesion also appears to be involved in tumor initiation, particularly in gastric carcinogenesis
