Back to aryl-ketone chemistry


  • "Schiff Base": A perturbating type (class) of imine.
  • "Active Methylene Enolate": A compound derived from an imide or product of a Micheal addition.

Schiff bases conjugated pharmacological intermediates and N-substituted heterocyclics carbenes

  • Present summarly the basic psychopharmacological aspects/functions of imine in a biological system .
    • pharmacological intermediates (N-substituted heterocyclics)
    • Nucleophilic carbonyl addition
    • PS: Yb(OTf)3 route to 1,2,3,4-tetrahydroisoquinolines derivatives.
    • Micheal addition=>PS (Pictet-Spengler asymmetric synthesis of 1,2,3,4-tetrahydroisoquinolines)

Schiff bases as quorum sensing molecules (AHL) and Serine-dependent osmolitic regulators/ATP synthase

  • Question 1 : In your own words, explain at least 2 functions of the envZ/30C6HSL (ATP-dependent) synthetase in E. coli.
  • Question 2 : How is EnvZ relevant to CES (ADA) and specifically the CAMK2G gene?
  • Note: Further info on Phenylmethylamine substituted beta-amyloid ligands (APP) are here.
  • Question 3 (bonus question) : In your own words, describe the role of a synthase enzyme (without the help of Wikipedia!) in the phosphorylation of ATP.

Troika acids; Formation of phenylmethylamine as the tautomeric form of a ethyl-methyl Carbanion (Cyanide) ligands : 4-trans-7-aminoalkylamino-2,1,3-benzoxadiazoles, 1,2-dimethylcyclohexanes and friends :)

The Monsanto connection: Troika acids; Novel cyanophosphonate compounds as disubstituted Schiff bases ?

  • US6218563 (cyanophosphonamides as recombinant polyhistidine tag)
  • US5935542 (cyanophosphonate derivatives compounds as a n-substituted Schiff base) (ie: for binding ca2+/mg2+ ions to a recombinant "fusion" protein...)
  • Chuck: If you want to spray civilians without impunity, be sure to include a cyanoethyl moeity...
  • Oracle: Are you kidding? Once upon a time cyanide was at the basis of the Zyklon-b pellet...
  • Oracle: Hence, the magnitude and scale of civilians exposure to the new compound is probably most effective today.
  • Chuck: For next time, how about a ban of spraying civilians with pharmacochemical intermediates ?
  • Oracle: Go ask Obama!
  • Chuck: LOL
  • Oracle: Go ask Monsanto! When should it become natural to breath air ? Is this a luxury reserved for an elite golf club ?
  • Chuck: And Is this the reason I'm being emprisonned ?
  • Chuck: Because I refuse to happily breath such things while the majority of the breed have no clue what the heck a troika acid is composed of?


  1. Imine (Schiff base) formation - Highly recommended primer documentation on Schiff bases
  2. http://www.wikigenes.org/e/chem/e/7046.html - 1,2,3,4-tetrahydroisoquinoline. (Note: A anti-malarial pharmaceutical compound comparable to mefloquine. Compound may be implicated in 4-trans like enantiomer substitution (conformational) leading to acute psychotic hallucinations. See: Arylcyclohexylamines and this document for a more concise explanation.)
