sf 11

SF 11 is a potent, brain-penetrant neuropeptide Y Y2 receptor antagonist with an IC50 of 199 nM, exhibiting antidepressant-like activity.

Aquastatin A is a fungal metabolite originally isolated fromF. aquaeductuumthat has diverse biological activities.1It is active againstS. aureus(MIC = 32 μg/ml) and inhibits enoyl-acyl carrier protein reductase (Fabl; IC50= 3.2 μM) andS. aureusfatty acid synthesis (IC50= 3.5 μM).2Aquastatin A also inhibits the Na+/K+-ATPase and H+/K+-ATPase (IC50s = 7.1 and 6.2 μM, respectively), as well as protein tyrosine phosphatase 1B (PTP1B; IC50= 0.19 μM).1,3 1.Hamano, K., Kinoshita-Okami, M., Minagawa, K., et al.Aquastatin A, an inhibitor of mammalian adenosine triphosphatases from Fusarium aquaeductuum.
