Drug profiling, or the ability to link batches of illicit drugs to a common source or synthetic route, has long been a goal of law enforcement agencies. Research in the past decade has explored drug profiling with isotope ratio mass spectrometry (IRMS). This type of research can be limited by the use of substances seized by police, of which the provenance is unknown. Fortunately, however, some studies in recent years have been carried out on drugs synthesized in-house and therefore of known history. In this study, 18 MDMA samples were synthesized in-house from aliquots of the same precursor by three common reductive animation routes and analyzed for 13C, 15N, and 2H isotope abundance using IRMS. For these three preparative methods, results indicate that 2H isotope abundance data is necessary for discrimination by synthetic route. Furthermore, hierarchical cluster analysis using 2H data on its own or combined with 13C and/or 15N provides a statistical means for accurate discrimination by synthetic route.

An environmentally friendly and highly diastereoselective method for synthesizing indanes has been developed via a metastable-state photoacid system containing catalytic protonated merocyanine (MEH). Under visible-light irradiation, MEH yields a metastable spiro structure and liberated protons, which facilitates the formation of carbocations from benzyl alcohols, thus delivering diverse molecules in the presence of various nucleophiles. Mainly, a variety of indanes could be easily obtained from benzyl alcohols and olefins, and water is the only byproduct.

Leishmaniasis, a neglected tropical disease with a high worldwide incidence, is considered a public health issue in Minas Gerais and Brazil, with a high degree of morbidity, not to mention the lack of therapeutic arsenal. The cysteine protease (rCPB2.8) and cyclin dependent kinase (CRK3), important enzymes for the parasite’s feasibility, were the targets chosen for investigation of the new drugs. The following study aimed to analyze several oximic derivatives starting from safrol, which can present an affinity profile for selected molecular targets using tools from molecular modeling and bioinformatics, planning and synthesis of brand new substances being tested for leishmanicidal drugs. The study allowed to verify that three oximic derivatives (5a, 5f and 5h) presented high affinity for the CRK3 enzyme, and that the compounds 5c and 5g presented good interaction by the amino acids of the catalytic site of the rCPB2.8 enzyme with atomic distances capable of generating covalent bonds, which are essential for enzyme inhibitory activity.

Ten imides derived from safrole, 4a-4j, were synthesized and their structures were fully characterized by infrared (IR) spectroscopy, 1H and 13C nuclear magnetic resonance (NMR) spectroscopy and high resolution mass spectrometry (HRMS) analysis. Among the ten imides studied, eight are new. The compounds were evaluated in an in silico study and showed strong to moderate antifungal activity against various strains of Candida and Cryptococcus. In particular, compounds 4b, 4c and 4h exhibited strong antifungal activity, with minimum inhibitory concentration (MICs) between 0.17-0.73 μmol mL-1. The compound 4j exhibited antifungal activity with MIC 1.28 μmol mL-1 for all strains tested. In silico studies of the parameters of Lipinski's rule of five indicated that these compounds are potential new drug candidates. The predict oral bioavailability can be evaluated through these parameters. In addition, a computational study helped assigning the stereochemistry of compound 4j, where the synthesized mixture is composed by two stereoisomers, 4j(1) (SRR) and 4j(2) (RSS).
