Anti-virulence drug discovery from natural bioactive compounds
Neem Biotech is a Wales-based drug discovery company developing novel non-traditional antimicrobial treatments derived from naturally inspired compounds.
The company specialises in quorum sensing inhibitors and anti-biofilm agents, with programmes targeting wound infection and cystic fibrosis.
Its discovery approach uses fragment screening coupled with expertise in bacterial-host interactions to identify small molecules that disrupt virulence rather than directly killing bacteria.
Neem has spun out subsidiary Mariposa Therapeutics for keratin-related skin disorders.
