The present invention provides methods and compositions for detecting, identifying and measuring the abundance of chemical nerve agents. Methods and compositions of the present invention are capable of providing selective detection of phosphorous based nerve agents, such as nerve agents that are esters of methyl phosphonic acid derivatives incorporating a moderately good leaving group at the phosphorus. Selectivity in the present invention is provided by a sensor composition having an alpha (α) effect nucleophile group that undergoes specific nucleophilic substitution and rearrangement reactions with phosphorus based nerve agents having a tetrahederal phosphorous bound to oxygen. The present invention includes embodiments employing a sensor composition further comprising a reporter group covalently linked to the alpha effect nucleophile group allowing rapid optical readout of nerve agent detection events, including direct visual readout and optical readout via spectroscopic analysis.

Oxalic acid-mediated conversion of alcohols to thiocyante and/or isothiocyanate is described. Aliphatic tertiary alcohols give isothiocyanate by the reaction with NaSCN in the presence of I2, whereas they give thiocyanate without it.

This invention offers an effective method of inhibiting the expression of apolipoprotein E by mammalian cells. Apolipoprotein E is a protein that plays a significant role in the development of Alzheimer's Disease in humans. The method comprises administering an effective amount of a triarylmethyl amine compound having the general formula:
wherein the R
1
group may comprise acyclic amines and aliphatic amines. The R
2
group may comprise one of three aryl varieties: aryl, substituted aryl, or heterocycle. Triarylamine compounds inhibit apolipoprotein E expression in mammalian cells. In one aspect of the invention the mammalian cells may be human cells, and more specifically may be human brain cells.
Trityl-type compounds comprise, bonded to the same atom, three aryl groups, of which at least one is a fluorophore and at least one has a substituent including a functional group, and wherein the compound can exist in a non-ionised state or in an ionised state conjugated with the aryl groups.
