Isoniazid (INH) is a first-line anti-tuberculosis drug used for nearly 70 years. However, the mechanism underlying the side effects of INH has remained elusive. Here, we report that INH and its metabolites induce a post-translational modification (PTM) of histones, lysine isonicotinylation (Kinic), also called 4-picolinylation, in cells and mice. INH promotes the biosynthesis of isonicotinyl-CoA (Inic-CoA), a co-factor of intracellular isonicotinylation. Mass spectrometry reveals 26 Kinic sites in histones in HepG2 cells. Acetyltransferases CREB-binding protein (CBP) and P300 catalyze histone Kinic, while histone deacetylase HDAC3 functions as a deisonicotinylase. Notably, MNase sensitivity assay and RNA-seq anal. show that histone Kinic relaxes chromatin structure and promotes gene transcription. INH-mediated histone Kinic upregulates PIK3R1 gene expression and activates the PI3K/Akt/mTOR signalling pathway in liver cancer cells, linking INH to tumorigenicity in the liver. We demonstrate that Kinic is a histone acylation mark with a pyridine ring, which may have broad biol. effects. Therefore, INH-induced isonicotinylation potentially accounts for the side effects in patients taking INH long-term for anti-tuberculosis therapy, and this modification may increase the risk of cancer in humans. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6SDS of cas: 1614-12-6).
1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. Triazoles are important five-member nitrogen heterocycles involved in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners, as well as biologically active agents. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeSDS of cas: 1614-12-6
