The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. Genetic defects in MTHFD1 may affect the risk of spina bifida via the maternal rather than the embryonic genotype. Genetic variation in MTHFD1 could be associated with susceptibility to colorectal cancer (CRC) [MIM:114500. Function C1TC_HUMAN Publication Abstract from PubMed Methylenetetrahydrofolate dehydrogenase/cyclohydrolase 2 (MTHFD2), a pivotal mitochondrial enzyme in one-carbon metabolism, is significantly upregulated in various cancers but minimally expressed in normal proliferating cells. In contrast, MTHFD1, which performs similar functions, is predominantly expressed in normal cells. Therefore, targeting MTHFD2 with selective inhibitors holds promise for a broader therapeutic window with reduced toxicity and fewer side effects. This study identified selective 2,4-diamino-6-oxo-1,6-dihydropyrimidin-5-yl ureido-based derivatives through systematic chemical modifications and SAR studies. Structural biology investigations revealed substitutions in the phenyl ring and tail region modulate potency and selectivity toward MTHFD2. Additionally, a comprehensive cell screening platform revealed acute myeloid leukemia cells with FLT3 internal tandem duplication mutations are particularly sensitive to these inhibitors. Furthermore, synergistic effects were observed when combining potential compounds with Alimta. Compound 16e emerged as a leading candidate, demonstrating superior inhibition and selectivity for MTHFD2, favorable pharmacokinetics, and potent antitumor efficacy in MOLM-14 xenograft models.
