An interesting enzyme of the endocannabinoid system is monoacylglycerol lipase (MAGL). This enzyme, which metabolizes the endocannabinoid 2-arachidonoylglycerol (2-AG), has attracted great interest due to its involvement in several physiological and pathological processes, such as cancer progression. Experimental evidences highlighted some drawbacks associated with the use of irreversible MAGL inhibitors in vivo, therefore the research field concerning reversible inhibitors is rapidly growing. In the present manuscript, the class of benzoylpiperidine-based MAGL inhibitors was further expanded and optimized. Enzymatic assays identified some compounds in the low nanomolar range and steered molecular dynamics simulations predicted the dissociation itinerary of one of the best compounds from the enzyme, confirming the observed structure-activity relationship. Biological evaluation, including assays in intact U937 cells and competitive activity-based protein profiling experiments in mouse brain membranes, confirmed the selectivity of the selected compounds for MAGL versus other components of the endocannabinoid system. An antiproliferative ability in a panel of cancer cell lines highlighted their potential as potential anticancer agents. Future studies on the potential use of these compounds in the clinical setting are also supported by the inhibition of cell growth observed both in cancer organoids derived from high grade serous ovarian cancer patients and in pancreatic ductal adenocarcinoma primary cells, which showed genetic and histological features very similar to the primary tumors.

An efficient and practical isatin-based oxidative domino protocol has been developed for the facile synthesis of 2-aminobenzamides and 2-aminobenzoates. The robust nature of this reaction system is reflected by accessible starting materials, room temperature and high-yield gram-scale synthesis.

Two volatile alkaloids, isopropyl N-methylanthranilate (IMA) and methyl N-methylanthranilate (MMA), present in the human diet and cosmetic products, were recently demonstrated to possess important pharmacological activities. While MMA is considered to be phototoxic, there is scarce data on the toxicity of IMA. Herein, we analyzed urinary metabolites of IMA and MMA in rats (200 mg kg?1, i.p., 7 days) by combining three different approaches: 1) preparative chromatography, 2) synthesis, and 3) SPR. The preparative approach, Sephadex LH-20 chromatography of the extract of urine samples of IMA treated animals, in conjunction with NMR, enabled the identification of 16 different anthranilate derivatives, among which products of aromatic core hydroxylation (isopropyl 5-hydroxy-N-methylanthranilate, isopropyl 5-hydroxyantranilate, isopropyl 3-hydroxyantranilate) were the major ones. The first application of the synthetic/combinatorial approach led to a successful identification of MMA metabolites, where 2-(methylamino)benzamide and N-methylanthranilic acid were the principal ones, among 14 others. Generally, MMA and IMA undergo analogous biotransformation pathways; however, MMA predominantly underwent chemical conversions of the ester group, i.e. transformation into derivatives of anthranilamide and anthranilic acid, while the major metabolic pathway of IMA was hydroxylation of the aromatic core. Additionally, pathohistological examinations revealed no signs of liver toxicity, or other signs of toxicity.

A two-step total synthesis of the neuroprotective alkaloid, dictyoquinazol A, has been achieved. The brevity of this synthesis was enabled by exploiting the hidden symmetry of the target molecule. Several structural analogues were also prepared using a similar strategy. These results provide a platform for future structure-activity relationship studies in the quest for a novel treatment for stroke.
