[https://www.uniprot.org/uniprot/MEN1_HUMAN MEN1_HUMAN] Defects in MEN1 are the cause of familial multiple endocrine neoplasia type I (MEN1) [MIM:[https://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:[https://omim.org/entry/145000 145000]; also known as hyperparathyroidism type 1 (HRPT1).

== Function ==
[https://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>

== Publication Abstract from PubMed ==
Development of potent small molecule inhibitors of protein-protein interactions with optimized druglike properties represents a challenging task in lead optimization process. Here, we report synthesis and structure-based optimization of new thienopyrimidine class of compounds, which block the protein-protein interaction between menin and MLL fusion proteins that plays an important role in acute leukemias with MLL translocations. We performed simultaneous optimization of both activity and druglike properties through systematic exploration of substituents introduced to the indole ring of lead compound 1 (MI-136) to identify compounds suitable for in vivo studies in mice. This work resulted in the identification of compound 27 (MI-538), which showed significantly increased activity, selectivity, polarity, and pharmacokinetic profile over 1 and demonstrated a pronounced effect in a mouse model of MLL leukemia. This study, which reports detailed structure-activity and structure-property relationships for the menin-MLL inhibitors, demonstrates challenges in optimizing inhibitors of protein-protein interactions for potential therapeutic applications.
