Mutagenic potency of MMS-induced 1meA/3meC lesions in E. coli. [PDF]
, 2009 The mutagenic activity of MMS in E. coli depends on the susceptibility of DNA bases to methylation and their repair by cellular defense systems. Among the lesions in methylated DNA is 1meA/3meC, which is recently recognized as being mutagenic.

Lethal and mutagenic properties of MMS-generated DNA lesions in Escherichia coli cells deficient in BER and AlkB-directed DNA repair. [PDF]
, 2010 Methylmethane sulphonate (MMS), an S(N)2-type alkylating agent, generates DNA methylated bases exhibiting cytotoxic and mutagenic properties. Such damaged bases can be removed by a system of base excision repair (BER) and by oxidative DNA demethylation ...

Experimental Studies with Methylhydrazine Derivatives [PDF]
Acta geneticae medicae et gemellologiae, 1968 SummaryNatulan (Procarbazine) is a methylhydrazine derivative which in animal experiments inhibits a series of transplantable tumours. The Walker carcinoma is markedly affected. Even well established Walker tumours disappear completely under Natulan treatment. Tumour tissue is replaced by fibrous tissue.

Angewandte Chemie, Volume 137, Issue 43, October 20, 2025.Herein we provide an overview of photochromic and photophysical properties of a broad variety of arylazo‐1,3,5‐trimethylpyrazole photoswitches, including the influence of 23 different para‐substituents. Measured half‐lives correlated in a Hammet plot are rationalized by density functional theory calculations, revealing the underlying thermal ...

A Fluorogenic Hydrazino‐Pictet–Spengler Reaction in Live Cells
Angewandte Chemie, Volume 137, Issue 40, September 26, 2025.A fluorogenic hydrazino‐Pictet–Spengler (HIPS) ligation reaction is used to label lipid‐derived aldehydes under wash‐free conditions in live cells. This innovative technique enables wash‐free imaging within biological systems, offering invaluable insights into the extent and localization of oxidative stress.
