Abstract:

Tuberculosis (TB) is a life-threatening infectious disease caused by Mycobacterium tuberculosis (Mtb). Globally, TB is a major public health burden with an estimated 10.4 million new cases and 1.8 million deaths reported in 2015. Although TB is curable, the treatment options currently available are beset by numerous shortcomings such as lengthy and complex treatment regimens, drug-drug interactions, drug toxicities, as well as emergence of widespread multi-drug resistance. Therefore, there is an urgent and compelling need to develop new, more effective, safer drugs with novel mechanisms of act

In this work a series of 11 <I>Rhodococcus</I> strains which mineralise the alkylphenone, 3-(2-hydroxyphenyl) propionic acid (OHP) were isolated from a larger strain collection previously isolated from a polluted gasworks in Newcastle, UK. These OHP catabolic pathways had not been subjected to direct selection during strain isolation and therefore are likely to represent the 'native' state of genes within the <I>Rhodococcus</I> genome.

Abstract:

A great number of pharmaceutical drugs target nucleic acids. However, drug-DNA interactions can be region non-specific and lead to undesired side effects. Understanding the mechanisms that regulate drug-DNA binding can help in the design of potent and selective therapeutic agents with fewer deleterious side effects. The present investigation explores the metal-mediated DNA binding of a group of 2-(2-hydroxyphenyl)benzoxazole (HPB) ligands and the aggregation dependant G-quadruplex selectivity of a series of perylene tetracarboxylic acid diimides (PTCDI) compounds. HPB ligands are simplified an

HL1 forms two different crystal phases, HL1-1 (orange color) and HL1-2 (colorless), both of which form intramolecular O-H…N hydrogen bonds, intermolecular N-H…O hydrogen bonds, and π−π stacking interations. However, the two phases pack in a linear and a staggered mammer, respectively
