l-menthyl

2'-Deoxycytidine is one of the major nucleosides of DNA consisting of cytosine and deoxyribose and inhibits the biological effects of bromodeoxyuridine (Brdu). The nucleoside consists only of a pentose sugar attached to a purine or pyrimidine base and has no phosphate group. When N1 is attached to C1 of deoxyribose, deoxyribosides and nucleotides are formed from cytosine and deoxyribose; deoxycytidine monophosphate (dCMP), deoxycytidine diphosphate (dCDP), and deoxycytidine triphosphate (dCTP). cTP is the source of cytosine in RNA (ribonucleic acid) and deoxycytidine triphosphate (dCTP) is the source of deoxycytidine in DNA (deoxyribonucleic acid). Itaconic acid is a polymer.

(+)-Menthyl acetate, extracted from the essential oil of Cunila angustifolia Benth, exhibits selective cytotoxicity, demonstrating higher efficacy against the MCF-7 cell line with an IC50 of 34.0 μg/mL and lower efficacy against the SK-Mel-28 cell line, where the IC50 is 279.9 μg/mL, when tested on A549 cells without fatal consequences [1].
