Highly regioselective 4-hydroxy-1-methylpiperidine mediated aromatic nucleophilic substitution on a perfluorinated phthalimide core

A tertiary amine-mediated highly regioselective aromatic nucleophilic substitution (SNAr) protocol was developed in the assemblies of perfluorinated phtalimide with primary or secondary amines as inputs. Application of 1-methyl-4-hydroxypiperidine as additive, formation of the less favoured, bioactive regioisomer was facilitated, modifying their ratios from the initial 8–36% to 81–91%. After optimization, a facile gram scale syntheses were accomplished and isolated the desired analogues in up to 63% yield.

COMPOUNDS AND COMPOSITIONS FOR LABELING LIPID DROPLETS, AND A METHOD FOR VISUALIZATION OF CELLS AND/OR CELLULAR ORGANELLES

The present patent relates to lipid droplet labeling compounds, having the general structure shown in formula I, (I) wherein X are each independently hydrogen, halogen, -C1-20-alkyl, -C2-20-alkenyl, -C2-20-alkinyl, -C5-6-cykloalkyl, aryl, aralkyl, adamantyl, heterocyclic, hydroxyl, hydroxyalkyl, Or -N-(R1, R2) group; n is 0, 1, 2, 3, or 4; R1 and R2 may each be independently hydrogen, straight or branching alkyl, cyclo-alkyl, aryl, aralkyl, heterocyclic group, wherein each is un-substituted or halogen substituted; or R1 and R2 together with the nitrogen in between them form a 5 or 6 member ring; A is a single bond, -O-, -S-, -CH2-, or -NH-; Y is O or S; Z is O or S; R' and R are each independently methyl, ethyl, isopropyl, isobuthyl, sec- butyl or terc-butyl. The patent also pertains to lipid droplet labeling compositions, which contain formula I and other additives or carriers. The invention further relates to a method for visualizing cells and/ or organelles with a fluorescent imaging technique, the method comprising: - labeling the cells and/ or organelles with one or more fluorescent compounds preferably being in the form of a solution, and - irradiating the cells and/or organelles with light of appropriate wavelength. The method is characterized by providing one or more fluorescent compounds having formula I for labeling the cells and/or organelles.
