Leptomycin B (LMB) is a potent inhibitor of the nuclear export of proteins and is a potent antifungal antibiotic blocking the eukaryotic cell cycle. Leptomycin B inactivates CRM1 exportin 1 by covalent modification at a cysteine residue.

N-Acetyl-L-glutamic acid (Ac-L-Glu-OH) (NAcGlu) is an acetylated amino acid. NAcGlu is biosynthesized from glutamic acid and acetyl-CoA by the enzyme N-acetyl glutamate synthase (NAGS). NAcGlu activates carbamoyl phosphate synthetase in the urea cycle. A deficiency in N-acetyl glutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in the blood leading to the condition called Type I hyperammonemia.

2'-Deoxyguanosine (Guanine deoxyriboside) is a purine nucleoside that is recognized by members of the 2'-dG-II family.2'-Deoxyguanosine has been associated with aging, mutation, and carcinogenesis, and is oxidized by molecular oxygen.

Clitocine, an adenosine analogue derived from mushrooms, is a potent transcriptional readout agent, an inhibitor of nonsense mutations, and has anticancer activity, inducing the production of p53 protein in cells carrying the p53 nonsense mutation allele.Clitocine enhances TRAIL-mediated apoptosis in human colon cancer cells by promoting Mcl-1 degradation.NSC 81464 is an alkaloid of the yohimbine type extracted from the roots and leaves of Rauwolfia vomitoria.

Aristolochic acid B (Aristolochic Acid II) is a natural product from the Aristolochaceae taxon and is one of the main components of aristolochic acid. Aristolochic acid is a mutagen and carcinogen, and Aristolochic acid B (Aristolochic Acid II) can show a greater carcinogenic risk in vivo than Aristolochic acid I.

Isocitric acid (Isocitrate), an isomer of citric acid, is a substrate for citric acid cycle and an endogenous metabolite, which has potential for the treatment of Parkinson’s disease, Fe-deficiency anemia, and metabolic myopathies associated with a shortage of succinate dehydrogenase and aconitate hydratase, as well as the mutation of the gene of NADP-dependent isocitrate dehydrogenase 1 (IDH1).

Alternaphenol B2, a selective inhibitor of mutant isocitrate dehydrogenase 1 (IDH1m), is sourced from the coral-derived fungus Parengyodontium album SCSIO SX7W11. It exhibits inhibitory activity specifically against the IDH1 R132H mutation, with an IC50 of 41.9 μM [1].
