[[http://www.uniprot.org/uniprot/MEN1_HUMAN MEN1_HUMAN]] Defects in MEN1 are the cause of familial multiple endocrine neoplasia type I (MEN1) [MIM:[http://omim.org/entry/131100 131100]]. Autosomal dominant disorder characterized by tumors of the parathyroid glands, gastro-intestinal endocrine tissue, the anterior pituitary and other tissues. Cutaneous lesions and nervous-tissue tumors can exist. Prognosis in MEN1 patients is related to hormonal hypersecretion by tumors, such as hypergastrinemia causing severe peptic ulcer disease (Zollinger-Ellison syndrome, ZES), primary hyperparathyroidism, and acute forms of hyperinsulinemia.<ref>PMID:14992727</ref> <ref>PMID:9989505</ref> <ref>PMID:9103196</ref> <ref>PMID:17555499</ref> <ref>PMID:9215689</ref> <ref>PMID:9215690</ref> <ref>PMID:9463336</ref> <ref>PMID:9683585</ref> <ref>PMID:9820618</ref> <ref>PMID:9671267</ref> <ref>PMID:10660339</ref> <ref>PMID:9506756</ref> <ref>PMID:9709921</ref> <ref>PMID:9709976</ref> <ref>PMID:9709985</ref> <ref>PMID:9740255</ref> <ref>PMID:9747036</ref> <ref>PMID:9832038</ref> <ref>PMID:10617276</ref> <ref>PMID:10229909</ref> <ref>PMID:10576763</ref> <ref>PMID:9888389</ref> <ref>PMID:10090472</ref> <ref>PMID:10534569</ref> <ref>PMID:10993647</ref> <ref>PMID:10849016</ref> <ref>PMID:10664520</ref> <ref>PMID:11102994</ref> <ref>PMID:11134142</ref> <ref>PMID:11241849</ref> <ref>PMID:12112656</ref> <ref>PMID:12417605</ref> <ref>PMID:12050235</ref> <ref>PMID:12699448</ref> <ref>PMID:12791038</ref> <ref>PMID:12652570</ref> <ref>PMID:14686752</ref> <ref>PMID:12746426</ref> <ref>PMID:15730416</ref> <ref>PMID:15714081</ref> Defects in MEN1 are the cause of familial isolated hyperparathyroidism (FIHP) [MIM:[http://omim.org/entry/145000 145000]]; also known as hyperparathyroidism type 1 (HRPT1).

[[http://www.uniprot.org/uniprot/MEN1_HUMAN MEN1_HUMAN]] Essential component of a MLL/SET1 histone methyltransferase (HMT) complex, a complex that specifically methylates 'Lys-4' of histone H3 (H3K4). Functions as a transcriptional regulator. Binds to the TERT promoter and represses telomerase expression. Plays a role in TGFB1-mediated inhibition of cell-proliferation, possibly regulating SMAD3 transcriptional activity. Represses JUND-mediated transcriptional activation on AP1 sites, as well as that mediated by NFKB subunit RELA. Positively regulates HOXC8 and HOXC6 gene expression. May be involved in normal hematopoiesis through the activation of HOXA9 expression (By similarity). May be involved in DNA repair.<ref>PMID:11526476</ref> <ref>PMID:11274402</ref> <ref>PMID:12874027</ref> <ref>PMID:12837246</ref> <ref>PMID:14992727</ref>

The structure-based design of M-525 as the first-in-class, highly potent, irreversible small-molecule inhibitor of the menin-MLL interaction is presented. M-525 targets cellular menin protein at sub-nanomolar concentrations and achieves low nanomolar potencies in cell growth inhibition and in the suppression of MLL-regulated gene expression in MLL leukemia cells. M-525 demonstrates high cellular specificity over non-MLL leukemia cells and is more than 30 times more potent than its corresponding reversible inhibitors. Mass spectrometric analysis and co-crystal structure of M-525 in complex with menin firmly establish its mode of action. A single administration of M-525 effectively suppresses MLL-regulated gene expression in tumor tissue. An efficient procedure was developed to synthesize M-525. This study demonstrates that irreversible inhibition of menin may be a promising therapeutic strategy for MLL leukemia.
