Polymyxin B nonapeptide, a cationic cyclic peptide derived by enzymatic processing from the naturally occurring peptide polymyxin B, is able to increase the permeability of the outer membrane of Gram-negative bacteria toward hydrophobic antibiotics probab
GGTI298 is a CAAZ peptidomimetic geranylgeranyltransferase I (GGTase I) inhibitor, strongly inhibiting the processing of geranylgeranylated Rap1A with little effect on processing of farnesylated Ha-Ras, with IC50 values of 3 and > 20 μM in vivo, respectively.
FTI-2153 is a potent and highly selective farnesyltransferase (FTase) inhibitor (IC50: 1.4 nM). FTI-2153 is >3000-fold more potent at blocking H-Ras (IC50, 10 nM) than Rap1A processing.
D-methionine sulfoxide hydrochloride, the D-isomer of methionine sulfoxide hydrochloride, is the oxidation product of methionine. Methionine is a restrictive amino acid in milk or legume proteins and is easily oxidized during storage.
