SMALL MOLECULE ALDEHYDE DEHYDROGENASE INHIBITORS AND METHODS OF USE THEREOF

Described herein are compounds, salts and solvates of the formula (I). Certain compounds of formula (I) are potent and selective inhibitors of aldehyde dehydrogenases (ALDH), a family of enzymes that play a critical role in detoxification of various cytot

Discovery of NCT-501, a Potent and Selective Theophylline-Based Inhibitor of Aldehyde Dehydrogenase 1A1 (ALDH1A1)

Aldehyde dehydrogenases (ALDHs) metabolize reactive aldehydes and possess important physiological and toxicological functions in areas such as CNS, metabolic disorders, and cancers. Increased ALDH (e.g., ALDH1A1) gene expression and catalytic activity are vital biomarkers in a number of malignancies and cancer stem cells, highlighting the need for the identification and development of small molecule ALDH inhibitors. A new series of theophylline-based analogs as potent ALDH1A1 inhibitors is described. The optimization of hits identified from a quantitative high throughput screening (qHTS) campaign led to analogs with improved potency and early ADME properties. This chemotype exhibits highly selective inhibition against ALDH1A1 over ALDH3A1, ALDH1B1, and ALDH2 isozymes as well as other dehydrogenases such as HPGD and HSD17β4. Moreover, the pharmacokinetic evaluation of selected analog 64 (NCT-501) is also highlighted.

Design and synthesis of EGFR dimerization inhibitors and evaluation of their potential in the treatment of psoriasis

Hit compounds from in silico screening for inhibitors of the EGFR dimerization process were evaluated for their anti-proliferative (CCD-1106 keratinocytes) and anti-oxidant (TBA assay) activity and their effect on EGFR dimerization (BS3 chemical crosslinking assay). 7-Benzyl-8-{N′- [1-(3-ethoxy-4-hydroxyphenyl)meth-(Z)-ylidene]hydrazino}-1,3-dimethylxanthine 2a (127 μM) leads to 37% inhibition of p-EGFR dimerization in the CCD-1106 cell line and also inhibits phosphorylation of proteins in the MAPK/ERK pathway, ERK 1/2 and p-38. Based on this initial data, 2a was selected for further study and was evaluated for its anti-proliferative activity in a range of keratinocyte (CCD-1106, HaCaT and NHEK) and monocyte (ThP1 and U937) cell lines. Xanthine 2a is pro-apoptotic in HaCaT keratinocytes, as shown by electron microscopy, caspase 3/7, and annexin V-FITC/PI flow cytometric assays. It is significantly less cytotoxic than the established antipsoriatic agent dithranol 14, as determined by MTT and LDH release assays, and thus has potential as a lead compound for the treatment of psoriasis.

8-(3-(R)-aminopiperidin-1-yl)-7-but-2-ynyl-3-methyl-1-(4-methyl-quinazolin- 2-ylmethyl)-3,7-dihydropurine-2,6-dione (BI 1356), a highly potent, selective, long-acting, and orally bioavailable DPP-4 inhibitor for the treatment of type 2 diabetes

A new chemical class of potent DPP-4 inhibitors structurally derived from the xanthine scaffold for the treatment of type 2 diabetes has been discovered and evaluated. Systematic structural variations have led to 1 (BI 1356), a highly potent, selective, long-acting, and orally active DPP-4 inhibitor that shows considerable blood glucose lowering in different animal species. 1 is currently undergoing clinical phase IIb trials and holds the potential for once-daily treatment of type 2 diabetics.

Synthesis of 8-substituted xanthine derivatives by Suzuki cross-coupling reaction

A Suzuki cross-coupling reaction procedure was developed to prepare 8-substituted 3,7-dihydropurine-2,6-dione (xanthine) derivatives. 8-Halogen-substituted xanthines were reacted with phenyl- and styrylboronic acids. The best results were obtained using tetrakis(triphenylphosphine)palladium(0) and tripotassium phosphate in dimethylformamide. The developed procedure allows for a convergent synthesis of pharmacologically active 8-substituted xanthine derivatives.
