Incyclinide (proposed trade name Metastat) is a chemically modified tetracycline antibiotic that was investigated in clinical trials for the treatment of rosacea,[1] various tumours, allergic and inflammatory diseases and a number of other conditions.[2][3]

Data from animal studies suggest that centrally infused incyclinide attenuates microglial mediated neuroinflammation in the paraventricular nucleus of the hypothalamus and sympathetic activation in angiotensin II-induced hypertension. This was also associated with unique changes in gut microbial communities and profound attenuation of gut pathology in animal models of hypertension.[4]

Mechanism of action

edit

Like other tetracyclines, incyclinide inhibits matrix metalloproteinases. In contrast to traditional tetracyclines, it lacks antibiotic properties.[5]
