Nemorosone (Nem) and guttiferone A (GutA) are acyl phloroglucinol derivatives (APD) that are present in different natural products. For both compounds anti-cancer and anti-microbial properties have been reported. In particular, an anti-leishmanial activity of both compounds was demonstrated. The aim

Amilorides, well-known inhibitors of Na(+)/H(+) antiporters, were previously shown to inhibit bacterial and mitochondrial NADH-quinone oxidoreductase (complex I) but were markedly less active for complex I. Because membrane subunits ND2, ND4, and ND5 of bovine complex I are homologous to Na(+)/H(+)

Biguanides are widely used antihyperglycemic agents for diabetes mellitus and prediabetes treatment. Complex I is the rate-limiting step of the mitochondrial electron transport chain (ETC), a major source of mitochondrial free radical production, and a known target of biguanides. Complex I has two r
A submitochondrial particle is a compartmentalized membranous product of exposing mitochondria to ultrasound. This causes the cristae to pinch off forcing the inner mitochondrial membrane inside out. As a consequence, the F1 particle ...
