Pharmacokinetics of Olivamide after Bolus Administration in Rats and Rabbits (a Pilot Study)
Антибиотики и Химиотерапия, 2020 The pharmacokinetics of olivamide, a semisynthetic antitumor derivate of olivomycin A, were studied in rats and rabbits after bolus administration. Plasma concentrations of olivamide were determined by an HPLC assay.

New antibiotics for antibiotic-resistant bacteria [PDF]
F1000 Biology Reports, 2009 The need for new antibiotics to effectively treat antibiotic-resistant infections remains unfulfilled. Despite the well-publicised concern over this issue, only two novel antibiotic classes have been introduced in the past 20 years alongside several new agents of existing classes.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure‐forward targeting of claudins with synthetic binders
FEBS Letters, EarlyView.Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Irumamicin Produced by Streptomyces roseoflavus INA-1278
Антибиотики и Химиотерапия, 2020 The strain Streptomyces roseoflavus INA-1278 is described as a new irumamicin producer. Irumamicin 1278 is different by the antifungal activity from irumamicin produced by the world-known strain Streptomyces subflavus subsp. Irumaensis subps. nov.
