CELL BIOLOGY: Building a Picket Fence

Violin timbre and the picket fence

A triazole-bearing picket fence type nickel porphyrin as a cyanide selective allosteric host.

A triazole-bearing picket fence type nickel porphyrin (1) has been synthesized as a host compound for anion binding. Among the various anionic species examined, cyanide was the only one that affected a spectral change of 1. Moreover, 1 exhibited strong homotropic positive allosterism against cyanide binding due to an electronic effect as well as multiple hydrogen bonds formed between cyanide an...

Photosensitizing activities of picket fence porphyrins in vitro and in vivo.

A set of structurally distinct o-substituted tetraphenylporphyrins, the picket fence porphyrins, were evaluated for their ability to photosensitize tumor mitochondria in vitro, in vivo-in vitro, and tumor implants in situ. Differential photosensitized inactivation efficiencies toward mitochondrial enzymes in vitro are reported for the 12 compounds studied as a function of side chain length and ...

Imagining the White Picket Fence: Social Class, Future Plans, and Romantic Relationship Quality

Previous research has established that individuals from a lower social class report lower relationship quality. However, to date, no studies have examined interdependence processes within the relationship as a mechanism underlying this association. The present research investigates the role of planned tangible investments as a mediator between social class and relationship quality. Across two s...

Building a path in cell biology

Setting up a new lab is an exciting but challenging prospect. We discuss our experiences in finding a path to tackle some of the key current questions in cell biology and the hurdles that we have encountered along the way.
