Timely New Information on Next-Generation Tetracyclines – Part 2: Eravacycline and Protein Binding

Posted on by — 2 Comments ↓

A recent paper by Thabit describes a curious finding [1]. The authors measured total and free (i.e., nonprotein-bound) eravacycline levels at ascending doses in a mouse model. They found strikingly small increases in free drug levels when titrating up total doses. The effect was rather dramatic: an increase in protein binding from 12% Continue reading Timely New Information on Next-Generation Tetracyclines – Part 2: Eravacycline and Protein Binding→

Timely New Information on Next-Generation Tetracyclines – Part 1: Omadacycline and Cardiac AEs

Posted on by — No Comments ↓

Several interesting articles appeared recently which shed light on the efficacy of eravacycline and the safety of omadacycline, both in Phase 3 and both in a head-to-head race to the market.  Well, the term ‘race’ is bit of a stretch as both drugs have seen very significant delays in development. Omadacycline from Continue reading Timely New Information on Next-Generation Tetracyclines – Part 1: Omadacycline and Cardiac AEs→

AZD-0914: A New Broad-Spectrum Narrow-Development Path Drug

Posted on by — No Comments ↓

At first glance, the list of features that distinguish AZD-0914 from other FQ seems impressive: broad Gram-positive and Gram-negative activity, MRSA and MSSA activity, potency against fluoroquinolone (FQ)-resistant isolates, low frequency for S. aureus resistance, and impressive activity against C. difficile. In addition, researchers mention a peculiar MoA for this gyrase/topoisomerase Continue reading AZD-0914: A New Broad-Spectrum Narrow-Development Path Drug→
