Analogues of 4-[(7-Bromo-2-methyl-4-oxo-3 H -quinazolin-6-yl)methylprop-2- ynylamino]- N -(3-pyridylmethyl)benzamide (CB-30865) as potent inhibitors of nicotinamide phosphoribosyltransferase (Nampt)

We have shown previously that the target of the potent cytotoxic agent 4-[(7-bromo-2-methyl-4-oxo-3H-quinazolin-6-yl)methyl-prop-2-ynylamino] -N-(3-pyridylmethyl)benzamide (CB38065, 1) is nicotinamide phosphoribosyltransferase (Nampt). With its cellular target known we sought to optimize the biochemical and cellular Nampt activity of 1 as well as its cytotoxicity. It was found that a 3-pyridylmethylamide substituent in the A region was critical to cellular Nampt activity and cytotoxicity, although other aromatic substitution did yield compounds with submicromolar enzymatic inhibition. Small unsaturated groups worked best in the D-region of the molecule, with 3,3-dimethylallyl providing optimal potency. The E region required a quinazolin-4-one or 1,2,3-benzotriazin-4-one group for activity, and many substituents were tolerated at C2 of the quinazolin-4-one. The best compounds showed subnanomolar inhibition of Nampt and low nanomolar cytotoxicity in cellular assays.

The design and synthesis of water-soluble analogues of CB30865, a quinazolin-4-one-based antitumor agent

4-[N-[7-Bromo-2-methyl-4-oxo-3,4-dihydroquinazolin-6-ylmethyl] -N-(prop-2-ynyl)amino]-N-(3-pyridylmethyl)benzamide (CB30865) is a quinazolin-4-one antitumor agent whose high growthinhibitory activity (W1L2 IC50 = 2.8 ± 0.50 nM) is believed to have a folate-independent locus of action. In addition, CB30865 represents a class of compounds with unique biochemical characteristics such as a delayed, non-phase specific, cell-cycle arrest. The low aqueous solubility of CB30865 prompted a search for more water-soluble analogues for in vivo evaluation of this class of compounds. It was thought that aqueous solubility could be increased by the introduction of amino functionalities at the 2-position of the quinazolin-4-one ring. A variety of compounds (5a-j, 31a-c, 32, and 33) were synthesized in a linear fashion starting from 3-chloro-4-methylaniline. Most of these compounds (e.g., 5a, 5b, 5g) were significantly more water-soluble than CB30865 (636 μM for 5a at pH 6 and 992 μM for 5g at pH 6). In addition, some of them were up to 6-fold more cytotoxic than CB30865 (e.g., for 5a, W1L2 IC50 = 0.49 ± 0.24 nM) and retained its novel biochemical characteristics.
