-
Page/Page column 16, (2018/06/30)
The invention pertains to the synthesis, isolation, and characterization of hemiaminal for selective labeling of peptides, proteins, antibodies, and organic fragments with -C(=0) CH2NH2 and derivatives with -CH2NH2 group over -C(=0) CHRNH2 group (where R≠H). The invention also pertains to the method of single-site immobilization of proteins through N-terminus Gly on solid phase. The invention includes late-stage tagging of N-terminus Gly with an affinity tag, 19F NMR probe, and a fluorophore and a method for metal-free protein purification and isolation of analytically pure proteins.

An efficient one-pot syntheses of aryl-3,3′-bis(indolyl)methanes (BIMs) from indole/2-methylindole and formylphenoxyaliphatic acid(s) is described. Esterification of carboxylic acid and aromatic electrophilic substitution reactions are achieved simultaneous in the presence of potash alum as a catalyst. This catalyst could be recovered and reused without substantial loss in its catalytic activity and the methodology could be applied on a range of closely related substrates. The solvation characteristics in ground and excited states of the compounds by monitoring the absorbance and fluorescence band maxima have been studied. The fluorescence studies in protic and aprotic solvents were rationalized on the basis of solute-solvent interaction and substituents effect on these photophysical processes analyzed. The compounds prepared showed efficient antimicrobial effect against human pathogens, cytotoxicity against A431 cell line, and DPPH radical scavenging effect. Single crystal XRD studies have been carried out for a few compounds synthesized in this work.

High throughput screening of Staphylococcus aureus phenylalanyl tRNA synthetase (FRS) identified ethanolamine 1 as a sub-micromolar hit. Optimisation studies led to the enantiospecific lead 64, a single-figure nanomolar inhibitor. The inhibitor series shows selectivity with respect to the mammalian enzyme and the potential for broad spectrum bacterial FRS inhibition.
