Benzylisoquinoline alkaloids (BIAs) are a structurally diverse family of plant secondary metabolites, which have been exploited to develop analgesics, antibiotics, antitumor agents, and other therapeutic agents. Biosynthesis of BIAs proceeds via a common pathway from tyrosine to (S)-reticulene at which point the pathway diverges. Coclaurine N-methyltransferase (CNMT) is a key enzyme in the pathway to (S)-reticulene, installing the N-methyl substituent that is essential for the bioactivity of many BIAs. In this paper, we describe the first crystal structure of CNMT which, along with mutagenesis studies, defines the enzymes active site architecture. The specificity of CNMT was also explored with a range of natural and synthetic substrates as well as co-factor analogues. Knowledge from this study could be used to generate improved CNMT variants required to produce BIAs or synthetic derivatives.

New verapamil analogues were synthesized and their inhibitory activities against Mycobacterium tuberculosis H37Rv determined in vitro alone and in combination with rifampicin (RIF). Some analogues showed comparable activity to verapamil and exhibited better synergies with RIF. Molecular docking studies of the binding sites of Rv1258c, a M. tuberculosis efflux protein previously implicated in intrinsic resistance to RIF, suggested a potential rationale for the superior synergistic interactions observed with some analogues.

Anti-headache chemistry: In the presence of a tailored modular P,P ligand the nickel-catalyzed addition of HCN, generated in situ from TMS-CN, to styrene derivatives proceeds with an unprecedented level of stereocontrol (up to 97 % ee) to give 2-aryl-acetonitriles, for example, the depicted precursor of Ibuprofen.
