Family of site-selective molecular optical switches
Sakata, Tomoyo,Yan, Yuling,Marriott, Gerard
, p. 2009 - 2013 (2005)
(Chemical Equation Presented) We describe the design, synthesis, and characterization of a family of thiol-reactive optical switches for labeling proteins and other biomolecules. Site-selective introduction of photochromic probes within biomolecules is be

Tautges, Brandon,Or, Victor,Garcia, Joel,Shaw, Jared T.,Louie, Angelique Y.
, p. 6569 - 6573 (2015)
In this work we synthesize molecular switches that are responsive to cysteine, homocysteine, and glutathione; three redox systems that make up the majority of the body's antioxidant defenses. Synthesized spiropyran isomers with conjugation-ready linkages

Spirobenzopyrans and spironaphthoxazins possessing a monoaza-crown ring were synthesized.Isomerization of these compounds to the open colored merocyanines was induced by recognition of alkali-metal cations and the selectivity of the coloration was found to be governed by several factors: (1) the size of the crown ring, (2) the position of recognition, (3) electric properties of both the complexed cations and the merocyanine dipoles, and (4) the length of the alkyl chains connecting the spirobenzopyran units and the crown units.The spirobenzopyrans represent rationally designed multifunctional receptors for alkali-metal cations.
Carbazole methyl malonates

, (2008/06/13)
A process for the preparation of α-methyl-carbazole-2-acetic acids, which comprises reacting an α-methyl-3-oxocyclohexane malonic acid di-lower alkyl ester with a substituted phenylhydrazine, and thereafter sequentially oxidizing and hydrolyzing the reaction product to obtain the desired acid, is described.
