[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).

[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>

BACKGROUND: Mixed lineage leukemia 1-rearranged (MLL1-r) acute leukemia patients respond poorly to currently available treatments and there is a need to develop more effective therapies directly disrupting the Menin‒MLL1 complex. Small-molecule-mediated inhibition of the protein‒protein interaction between Menin and MLL1 fusion proteins is a potential therapeutic strategy for patients with MLL1-r or mutated-nucleophosmin 1 (NPM1c) acute leukemia. In this study, we preclinically evaluated the new compound DS-1594a and its salts. METHODS: We evaluated the preclinical efficacy of DS-1594a as well as DS-1594a.HCl (the HCl salt of DS-1594a) and DS-1594a.succinate (the succinic acid salt of DS-1594a, DS-1594b) in vitro and in vivo using acute myeloid leukemia (AML)/acute lymphoblastic leukemia (ALL) models. RESULTS: Our results showed that MLL1-r or NPM1c human leukemic cell lines were selectively and highly sensitive to DS-1594a.HCl, with 50% growth inhibition values &lt; 30 nM. Compared with cytrabine, the standard chemotherapy drug as AML therapy, both DS-1594a.HCl and DS-1594a.succinate mediated the eradication of potential leukemia-initiating cells by enhancing differentiation and reducing serial colony-forming potential in MLL1-r AML cells in vitro. The results were confirmed by flow cytometry, RNA sequencing, RT‒qPCR and chromatin immunoprecipitation sequencing analyses. DS-1594a.HCl and DS-1594a.succinate exhibited significant antitumor efficacy and survival benefit in MOLM-13 cell and patient-derived xenograft models of MLL1-r or NPM1c acute leukemia in vivo. CONCLUSION: We have generated a novel, potent, orally available small-molecule inhibitor of the Menin-MLL1 interaction, DS-1594a. Our results suggest that DS-1594a has medicinal properties distinct from those of cytarabine and that DS-1594a has the potential to be a new anticancer therapy and support oral dosing regimen for clinical studies (NCT04752163).
