- SUBSTITUTED BICYCLIC PYRIMIDINE-BASED COMPOUNDS AND COMPOSITIONS AND USES THEREOF
-
Novel C-2-substituted bicyclic compounds of Formula I have been prepared and found to be useful as potent inhibitors of hGGPPS by inhibiting geranylgeranylation of proteins and inhibiting the biosynthesis of GGPP. The application is directed to these compounds, to compositions comprising these compounds, and to their use, in particular as medicaments for use in the treatment of cancer and other conditions which are treatable by inhibiting human geranylgeranylation pyrophosphate hGGPPS activity.

- Discovery of a First-in-Class, Potent, Selective, and Orally Bioavailable Inhibitor of the p97 AAA ATPase (CB-5083)
-
The AAA-ATPase p97 plays vital roles in mechanisms of protein homeostasis, including ubiquitin-proteasome system (UPS) mediated protein degradation, endoplasmic reticulum-associated degradation (ERAD), and autophagy. Herein we describe our lead optimization efforts focused on in vitro potency, ADME, and pharmaceutical properties that led to the discovery of a potent, ATP-competitive, D2-selective, and orally bioavailable p97 inhibitor 71, CB-5083. Treatment of tumor cells with 71 leads to significant accumulation of markers associated with inhibition of UPS and ERAD functions, which induces irresolvable proteotoxic stress and cell death. In tumor bearing mice, oral administration of 71 causes rapid accumulation of markers of the unfolded protein response (UPR) and subsequently induces apoptosis leading to sustained antitumor activity in in vivo xenograft models of both solid and hematological tumors. 71 has been taken into phase 1 clinical trials in patients with multiple myeloma and solid tumors.

- FUSED PYRIMIDINES AS INHIBITORS OF p97 COMPLEX
-
Fused pyrimidine compounds having a saturated, unsaturated or aromatic A ring fused to a pyrimidine ring and having a complex substituents at the 2 position and a substituted amine at the 4 position of the pyrimidine ring as well as optional aliphatic, functional and/or aromatic components substituted at other positions of the pyrimidine ring and A ring are disclosed. These compounds are inhibitors of the AAA proteasome complex containing p97 and are effective medicinal agents for treatment of diseases associated with p97 bioactivity such as cancer.
