Novel 2,7-Dialkyl-Substituted 5(S)-Amino-4(S)-hydroxy-8-phenyl-octanecarboxamide Transition State Peptidomimetics Are Potent and Orally Active Inhibitors of Human Renin
摘要:
The action of renin is the rate-limiting step of the renin-angiotensin system (RAS), a key regulator of blood pressure. Effective renin inhibitors directly block the RAS entirely at source and, thus, may provide a vital weapon for hypertension therapy. Our efforts toward identifying novel small-molecule peptidomimetic renin inhibitors have resulted in the design of transition-state isosteres such as I bearing an all-carbon 8-phenyl-octanecarboxamide framework. Optimization of the extended P3 portion of I and extensive P2' modifications provided analogues with improved in vitro potencies in the presence of plasma. X-ray resolution of rhrenin/38a in the course of SAR work surprisingly unveiled the exploitation of a previously unexplored pocket (S3(SP)) important for strong binding affinities. Several inhibitors demonstrated oral efficacy in sodium-depleted marmosets. The most potent, 38a, induced dose-dependently a pronounced reduction in mean arterial blood pressure, paralleled by complete blockade of active plasma renin, up to 8 h post-dose. Oral bioavailability of 38a was 16% in marmosets.

HIV-EP1 is a C2H2 type zinc finger proteinwhich binds to DNA kappa B site present in the long terminal repeat of HIV provirus. Previously we have reported zincchelators having histidine--pyridine--histidine skeleton and were successful in inhibiting the DNA binding of HIV-EP1 by removing zinc from the zinc finger domain. Aiming at the potentiation of the inhibitory activity of our previous zinc chelators
Compositions and methods related to targeted carbon nanostructures. More particularly, targeted carbon nanostructures comprising: a C
n
, a cross-linker, and a targeting agent, wherein C
n
refers to a fullerene moiety or nanotube comprising n carbon atoms. One example of a method may involve a method for imaging comprising: contacting a targeted carbon nanostructure and a cell; allowing the cell to internalize the carbon nanostructure; and detecting the presence of internalized carbon nanostructures.
