Murepavadin

How it works

An antibiotic designed to hit LptD, an outer-coat protein that only Pseudomonas bacteria have in this form. Sniper, not shotgun.

What it's made of

14 amino acids in a hairpin-shaped ring, designed from protegrin I, a natural antimicrobial. It was redesigned not to burst membranes and to attack a single protein, LptD, which only Pseudomonas has in this form.

What it's for

Prescribed for

Nothing.

Sold as

A sniper antibiotic: it only kills Pseudomonas, even the ones that already resist colistin.
