JHU395 is a novel orally bioavailable GA (glutamine antagonists) prodrug designed to circulate inert in plasma, but permeate and release active GA within target tissues. JHU395 delivers active GA to malignant peripheral nerve sheath tumor (MPNST), and significantly inhibits tumor growth without observed toxicity.
JHU395 inhibits growth of multiple biosynthetic processes by tumors (MPNST) cells, while growth of immortalized Schwann cells is minimally affected. JHU395 induces less PARP cleavage as a marker of apoptosis in human MPNST cells. JHU395 is a plasma stable lipophilic GA prodrug which delivers DON to MPNST in an in vitro plasma to tumor cell partitioning assay measurement.[1]
In vivo, orally administered JHU395 delivers active GA to tumors with over twofold higher tumor-to-plasma exposure, and significantly inhibits tumor growth in a murine flank MPNST model without observed toxicity.[1]

Novel Glutamine Antagonist JHU395 Suppresses MYC-Driven Medulloblastoma Growth and Induces Apoptosis
J Neuropathol Exp Neurol 2021 Mar 22;80(4):336-344.PMID:33712838DOI:10.1093/jnen/nlab018.
Medulloblastoma is the most common malignant pediatric brain tumor. Amplification of c-MYC is a hallmark of a subset of poor-prognosis medulloblastoma. MYC upregulates glutamine metabolism across many types of cancer. We modified the naturally occurring glutamine antagonist 6-diazo-5-oxo-l-norleucine (DON) by adding 2 promoeities to increase its lipophilicity and brain penetration creating the prodrug isopropyl 6-diazo-5-oxo-2-(((phenyl (pivaloyloxy) methoxy) - carbonyl) amino) hexanoate, termed JHU395. This prodrug was shown to have a 10-fold improved CSF-to-plasma ratio and brain-to-plasma ratio relative to DON. We hypothesized that JHU395 would have superior cell penetration compared with DON and would effectively and more potently kill MYC-expressing medulloblastoma. JHU395 treatment caused decreased growth and increased apoptosis in multiple human high-MYC medulloblastoma cell lines at lower concentrations than DON. Parenteral administration of JHU395 in Nu/Nu mice led to the accumulation of micromolar concentrations of DON in brain. Treatment of mice bearing orthotopic xenografts of human MYC-amplified medulloblastoma with JHU395 increased median survival from 26 to 45 days compared with vehicle control mice (p < 0.001 by log-rank test). These data provide preclinical justification for the ongoing development and testing of brain-targeted DON prodrugs for use in medulloblastoma.
The Novel Glutamine Antagonist Prodrug JHU395 Has Antitumor Activity in Malignant Peripheral Nerve Sheath Tumor
Mol Cancer Ther 2020 Feb;19(2):397-408.PMID:31594823DOI:10.1158/1535-7163.MCT-19-0319.
The carbon and nitrogen components of glutamine are used for multiple biosynthetic processes by tumors. Glutamine metabolism and the therapeutic potential of glutamine antagonists (GA), however, are incompletely understood in malignant peripheral nerve sheath tumor (MPNST), an aggressive soft tissue sarcoma observed in patients with neurofibromatosis type I. We investigated glutamine dependence of MPNST using JHU395, a novel orally bioavailable GA prodrug designed to circulate inert in plasma, but permeate and release active GA within target tissues. Human MPNST cells, compared with Schwann cells derived from healthy peripheral nerve, were selectively susceptible to both glutamine deprivation and GA dose-dependent growth inhibition. In vivo, orally administered JHU395 delivered active GA to tumors with over 2-fold higher tumor-to-plasma exposure, and significantly inhibited tumor growth in a murine flank MPNST model without observed toxicity. Global metabolomics studies and stable isotope-labeled flux analyses in tumors identified multiple glutamine-dependent metabolites affected, including prominent effects on purine synthesis. These data demonstrate that glutamine antagonism is a potential antitumor strategy for MPNST.
