Monoacylglycerol lipase (MAGL) is the enzyme degrading the endocannabinoid 2-arachidonoylglycerol, and it is involved in several physiological and pathological processes. The therapeutic potential of MAGL is linked to several diseases, including cancer. The development of MAGL inhibitors has been greatly limited by the side effects associated with the prolonged MAGL inactivation. Importantly, it could be preferable to use reversible MAGL inhibitors in vivo, but nowadays only few reversible compounds have been developed. In the present study, structural optimization of a previously developed class of MAGL inhibitors led to the identification of compound 23, which proved to be a very potent reversible MAGL inhibitor (IC50 = 80 nM), selective for MAGL over the other main components of the endocannabinoid system, endowed of a promising antiproliferative activity in a series of cancer cell lines and able to block MAGL both in cell-based as well as in vivo assays.

Several N-isopropyliodobenzamides were evaluated as catalysts for the oxidation of benzhydrol to benzophenone in the presence of Oxone (2KHSO5·KHSO4·K2SO4) as a co-oxidant at room temperature. A study on the substituent effect of the benzene ring of N-isopropyl-2-iodobenzamide on the oxidation revealed that its reactivity increased in the following order of substitution: 5-NO2 2Me, 3-OMe 5-OAc 5-Cl H, 4-OMe 5-Me 5-OMe. The oxidation of various benzylic and aliphatic alcohols using a catalytic amount of the most reactive 5-methoxy derivative successfully resulted in moderate to excellent yields of the corresponding carbonyl compounds. The high reactivity of the 5-methoxy derivative at room temperature is a result of the rapid generation of the pentavalent species from the trivalent species during the reaction. 5-Methoxy-2-iodobenzamide would be an efficient and environmentally benign catalyst for the oxidation of alcohols, especially benzylic alcohols.

A variety of cyclic sulfonamides and sulfinamides could be selectively synthesized under Pd catalysis using haloarenes bearing amino groups and a sulfur dioxide (SO2) surrogate. The amount of base was key in determining the selectivity. Mechanistic studies revealed that sulfinamides were initially formed via an unprecedented formal insertion of sulfur monoxide and were oxidized to sulfonamides in the presence of an iodide ion and DMSO.
