De Minimis - 2811 / 6.1

Istradefylline is an adenosine receptor 2A (A2A) antagonist (Ki = 2.2 nM in a radioligand binding assay).{37122} In vivo, istradefylline inhibits catalepsy induced by haloperidol (Item No. 12014) with an ED50 value of 0.23 mg/kg in rats. Oral administration of istradefylline alleviates postural defects in a dose-dependent manner without inducing dyskinesias or hyperactivity in an MPTP-induced marmoset model of Parkinson’s disease.{37123} It also decreases bradykinesias induced by L-DOPA (Item No. 13248) and improves attentional and working memory deficits in an MPTP-induced macaque model of Parkinson’s disease.{37124} Formulations containing istradefylline are used to extend on-time in Parkinson’s disease patients experiencing motor fluctuations.

    CAY10512 – 500 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 500 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
