Starting from a prototypical structure 1, we describe our efforts to design and obtain novel quinazoline/pyrimidine-2,4(1H,3H)-diones with high CB2 agonist potency and selectivity as well as improved physicochemical characteristics, mainly hydrophilicity. The most potent and selective CB2 agonists, 8 and 36, in this series were also endowed with lower logP values than that of GW842166X and lead compound 1. These derivatives appear to be promising lead compounds for the development of future CB2 agonists.

Given the clinical importance of metallo-β-lactamases (MβLs), a new scaffold, N-substituted carbamylmethyl mercaptoacetate thioether, was constructed. The obtained molecules 1-16 inhibited MβLs from all three subclasses, but preferentially L1 from subclass B3. Compound 9 with a p-carboxyphenyl substituent exhibited the broadest spectrum with at least 70% inhibition of enzymes from all subclasses at 100 μM, while compound 5 with a p-methylphenyl substituent was the most potent inhibitor of any individual enzyme, with 97% inhibition at 100 μM and an IC50 value of 0.41 μM against L1. Isothermal titration calorimetry assays corroborate findings from UV-vis spectrophotometric assays that the inhibition of L1 by 5 is dose-dependent. Docking studies suggest that the carboxyl group, the sulfide atom, and the carbonyl group of the carbamyl coordinate Zn2 in a chelating fashion. Using E. coli cells expressing L1, 6 and 8 were able to decrease cefazolin minimum inhibitory concentration 8-fold.

Stereoselective synthesis of naturally occurring unsaturated amide alkaloids by a modified Ramberg-Baecklund reaction

, p. 622 - 630 (2007/10/03)
A convenient and rapid approach for the synthesis of naturally occurring unsaturated amide alkaloids 1a-1n by the recently developed one-flask Ramberg-Baecklund reaction is described. The starting material was alcohol 3, which was transformed into thiolacetate 4 using the Mitsunobu reaction. In situ cleavage of acetyl moiety of 4, followed by alkylation of the resulting thiol with appropriate chloroacetamide 5, provided the sulfide 6. Oxidation of sulfide 6 gave the corresponding sulfone 2. Treatment of the sulfone 2 with the dibromodifluoromethane in the presence of alumina-supported potassium hydroxide in dichloromethane solution afforded unsaturated amide alkaloids 1a-1n. To the best of our knowledge, the synthesis of 1e and 1i was reported for the first time.
