Process Optimisation Studies and Aminonitrile Substrate Evaluation of Rhodococcus erythropolis SET1, A Nitrile Hydrolyzing Bacterium
Coady, Tracey M.,Coffey, Lee,Kinsella, Michael,Lennon, Claire M.,Mareya, Tatenda M.,O'Reilly, Catherine
, p. 512 - 520 (2020/10/02)
A comprehensive series of optimization studies including pH, solvent and temperature were completed on the nitrile hydrolyzing Rhodococcus erythropolis bacterium SET1 with the substrate 3-hydroxybutyronitrile. These identified temperature of 25 °C and pH of 7 as the best conditions to retain enantioselectivity and activity. The effect of the addition of organic solvents to the biotransformation mixture was also determined. The results of the study suggested that SET1 is suitable for use in selected organo-aqueous media at specific ratios only. The functional group tolerance of the isolate with unprotected and protected β-aminonitriles, structural analogues of β-hydroxynitriles was also investigated with disappointingly poor isolated yields and selectivity obtained. The isolate was further evaluated with the α- aminonitrile phenylglycinonitrile generating acid in excellent yield and ee (>99 % (S) – isomer and 50 % yield). A series of pH studies with this substrate indicated pH 7 to be the optimum pH to avoid product and substrate degradation.

supporting information, p. 2882 - 2887 (2019/02/17)
The synthesis and gelation properties of chiral β-amino acid-based low-molecular-weight organogelators, possessing methyl/trifluoromethyl side chains, are reported. The structure of the side chain and chirality were found to be important parameters affecting the gelation ability. The pure enantiomer of the trifluoromethylated β-amino acid displayed good gelation properties due to the formation of fibrillar networks, driven by enhanced amide hydrogen bonding. An investigation of the effects of the alkyl chain length showed that longer alkyl chain improved the gelation ability, yet the same supramolecular structure was observed in all, as well as an odd-even effect in both the melting points and Tg values.

A multifaceted secondary structure mimic based on piperidine-piperidinones

Minimalist secondary structure mimics are typically made to resemble one interface in a protein-protein interaction (PPI), and thus perturb it. We recently proposed suitable chemotypes can be matched with interface regions directly, without regard for secondary structures. Here we describe a modular synthesis of a new chemotype 1, simulation of its solution-state conformational ensemble, and correlation of that with ideal secondary structures and real interface regions in PPIs. Scaffold 1 presents amino acid side-chains that are quite separated from each other, in orientations that closely resemble ideal sheet or helical structures, similar non-ideal structures at PPI interfaces, and regions of other PPI interfaces where the mimic conformation does not resemble any secondary structure. 68 different PPIs where conformations of 1 matched well were identified. A new method is also presented to determine the relevance of a minimalist mimic crystal structure to its solution conformations. Thus dld-1-faf crystallized in a conformation that is estimated to be 0.91 kcal-mol-1 above the minimum energy solution state. Do we know, when designing a new peptidomimetic scaffold like the one shown, how it can resemble secondary structures? Design and modular synthesis of this elongated mimic is reported, and the structure is related to ideal and real structures at PPI interfaces.

A series of CCR5 antagonists were optimized for potent inhibition of R5 HIV-1 replication in peripheral blood mononuclear cells. Compounds that met acceptable ADME criteria, selectivity, human plasma protein binding, potency shift in the presence of α-glycoprotein were evaluated in rat and dog pharmacokinetics.
