Boscalid is a broad-spectrum carboxamide fungicide that inhibits fungal respiration by binding to the ubiquinone site of mitochondrial complex II/succinate dehydrogenase.1It suppresses mycelial growth ofS. minorby 87 to 100% and ofS. sclerotiorumby 77 to 100% when used at a concentration of 1 μg/ml.2In field studies, boscalid applied at 5.6 μg/cm2provides 55.5 and 30.4% disease control for lettuce drop caused byS. minorandS. sclerotiorum, respectively. It decreases cell viability of mouse primary cortical neurons following long-term exposure but is not cytotoxic (LC50= >100 μM for acute and continuous exposure). Formulations containing boscalid have been used in agriculture to prevent fungal growth on crops. 1.Wang, Y., Duan, Y., Wang, J., et al.A new point mutation in the iron-sulfur subunit of succinate dehydrogenase confers resistance to boscalid in Sclerotinia sclerotiorumMol.

D-Glucaric acid potassium (D-Saccharic acid potassium salt) is a compound formed from oxidizing sugars, which can be used to test for the presence of hepatic enzyme induction. Studies indicate that D-glucuronolactone dehydrogenase oxidizes D-Saccharic acid potassium salt into D-glucaro-l,4;6,3-dilactone. Alternate studies suggest that D-Saccharic acid potassium salt forms a complex with Cu(II) and H2O2to decolorize azo, acridine, triphenyl methane, anthraquinone and thiazine-based dyes.

Malonic acid (propanedioic acid) is the archetypal example of a competitive inhibitor: it acts against succinate dehydrogenase (complex II) in the respiratory electron transport chain. Malonic acid is found to be associated with malonyl-CoA decarboxylase deficiency, which is an inborn error of metabolism.

CLIP 86-100 acetate(648881-58-7 free base) is amino acids 86 to 100 fragment of class II-associated invariant chain peptide called CLIP. The major histocompatibility complex class II molecule displays peptide fragments of foreign proteins to trigger a defensive reaction from the immune system. Before insertion of the foreign peptides into the binding groove, a place-holding peptide CLIP is removed. CLIP 86-100 acetate(648881-58-7 free base) is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.
