Provided herein are antibacterial compounds, wherein the compounds in some embodiments have broad spectrum bioactivity. In various embodiments, the compounds act by inhibition of lipoprotein signal peptidase II (LspA), a key protein in bacteria. Pharmaceutical compositions and methods for treatment using the compounds described herein are also provided.
New Dual Inhibitors of Neutral Endopeptidase and Angiotensin-Converting Enzyme: Rational Design, Bioavailability, and Pharmacological Responses in Experimental Hypertension
molecules and the ACE template. New dual inhibitors, of general formula, N-[2(R,S)-(mercaptomethyl)-3(R,S)-phenylbutanoyl]-L-amino acid with IC50 values in the nanomolar range for both enzymes were generated by this approach. The separation of the four stereoisomers using chiral amines and the stereoselective synthesis of the 2-(mercaptomethyl)-3-phenylbutanoyl moiety showed that inhibitors with the 2S,3R configuration
A substance capable of imparting a kokumi having CaSR agonist activity is described. This substance is able to impart kokumi in a superior manner, in particular, at the initial taste, and is also highly stable and can easily be produced at a low cost. The present invention thus provides a kokumi-imparting composition which includes such a substance as well as a complex kokumi-imparting composition which includes the substance and other substances possessing the CaSR agonist activities in combination. More particularly, the present invention herein provides a kokumi-imparting composition including γ-Glu-Nva (L-γ-glutamyl-L-norvaline), and a complex kokumi-imparting composition including the foregoing substance and another substance having a CaSR agonist activity, in combination.
