D-methioninesulfoxidehydrochloride, the D-isomer of methioninesulfoxidehydrochloride, is the oxidation product of methionine. Methionine is a restrictive amino acid in milk or legume proteins and is easily oxidized during storage.
1,4-Dideoxy-1,4-imino-D-arabinitol (DAB) functions as an inhibitor of glycogen phosphorylase, a crucial enzyme in glycogenolysis, demonstrating the ability to hinder this process in isolated liver cells (IC50= 1.0 µM) and cerebral cortex and cerebellum homogenates (IC50s = 463 and 383 nM, respectively). Employed extensively in different animal models, DAB inhibits glycogenolysis within the liver and brain.
N(G)-Nitro-D-arginine methyl ester (D-NAME) is the less active enantiomer of the nitric oxide (NO) synthase inhibitor N(G)-nitro-L-arginine methyl ester . D-NAME was initially thought to be inactive and was often used as a negative control for L-NAME. Later studies showed that D-NAME (40 mg/kg/day in rats) can have similar but less pronounced effects as L-NAME (40 mg/kg/day in rats) in the cardiovascular system, particularly at long-term timepoints. D-NAME (3-10 µg/mouse) had no effect on nociception in mice assessed using the tail flick test.
(+)-D-threo-PDMP is a ceramide analog and is one of the four possible stereoisomers of PDMP . (+)-D-threo-PDMP is an inhibitor of glucosylceramide synthase. It inhibits glucosylceramide synthase by 50% when used at a concentration of 5 μM in an enzyme assay. (+)-D-threo-PDMP is the active component of racemic DL-threo-PDMP .
D-threo-PPMP is a glucosylceramide (GlyCer) synthetase inhibitor.1,2It is the active enanantiomer and enzymatic inhibitory component of the racemic DL-threo-PPMP . In MDCK kidney epithelial cells, D-threo-PPMP induces a 70% reduction in cell growthin vitroat 20 μM and significantly inhibits DNA synthesis at 3 μM.3[Matreya, LLC.

D-Cl-amidine hydrochloride is a potent and highly selective inhibitor of PAD1. It exhibits excellent tolerance and does not induce significant toxicity [1].
D-2-Aminoglutarimide is a synthetic intermediate.1It has been used in the synthesis of hydantoins with anti-angiogenic and cancer cell differentiation-inducing activities. 1.Yamaguchi, J., Noguchi-Yachide, T., Sakaguchi, Y., et al.Synthesis of new hydantoins bearing glutarimide or succinimide moiety and their evaluation for cell differentiation-inducing and anti-angiogenic activitiesHeterocycles91(4)764-781(2015)
H-D-Phe-Pip-Arg-pNA hydrochloride, a chromogenic substrate, mimics the N-terminal segment of the A alpha chain of fibrinogen, the native substrate of thrombin. It displays specificity towards thrombin and is employed for quantifying antithrombin-heparin cofactor (AT-III). The utilization of H-D-Phe-Pip-Arg-pNA hydrochloride in the AT-III assay enables a sensitive, accurate, and straightforward measurement process.
1-Amino-1-deoxy-D-fructose is an amino monosaccharide.1It induces site-specific DNA damage at pyrimidine residues in cell-free assays. 1-Amino-1-deoxy-D-fructose moieties have been found as a component of fructosamines, glycated serum proteins that are elevated in patients with conditions such as diabetes.2,3
D-Mabuterol hydrochloride is a D isoform of Mabuterol, which is a selective β2 adrenoreceptor agonist. Mabuterol has been found to decrease the blood pressure in rats and increase heart rate and contractile force in guinea pigs. Mabuterol inhibited the positive inotropic effect of isoprenaline but has no effect on alpha-adrenergic, acetylcholine and histamine receptors.
