Reaction of dichlorocarbene with cis-l,4-polyisoprene

Antithrombin activity of a polyelectrolyte synthesized from cis-1,4-polyisoprene.

Dielectric Behavior of cis-Polyisoprene in Carbon Dioxide under High Pressure

Dielectric measurement was conducted for cis-polyisoprene (PIP) in carbon dioxide (CO2) at high pressures. CO2 is dissolved in PIP more with increasing pressure, and this dissolution is expected to affect the chain dynamics. In our experimental window, the PIP chains having type-A dipoles parallel along their backbone exhibited the dielectric dispersion reflecting their global motion. This disp...

Introducing dichlorocarbene in graphene.

The functionalization of graphene with dichlorocarbene has been successfully attained based on a conventional method for the generation of dichlorocarbenes. The obtained material was fully characterized using high resolution X-ray photoelectron spectroscopy, transmission electron microscopy, infrared and Raman spectroscopies.

Reaction of prostaglandin endoperoxide synthase with cis,cis-eicosa-11,14-dienoic acid.

The pre-steady-state phase of the oxygenase reaction of prostaglandin endoperoxide synthase with cis,cis-eicosa-11, 14-dienoic acid has been studied using stopped flow techniques. Because some intermediate forms of prostaglandin endoperoxide synthase are spectrally indistinguishable, the enzyme and substrate transformations were monitored in parallel to simplify the interpretation of the kineti...

Effect of 2-(3,4-Dichlorophenoxy)-triethylamine on the Synthensis of cis-Polyisoprene in Guayule Plants (Parthenium argentatum Gray).

The application of 2-(3,4-dichlorophenoxy)-triethylamine to guayule (Parthenium argentatum Gray var 593) plants results in a 2-fold stimulation of rubber synthesis and a 1.5- to 3-fold increase in mevalonic acid kinase, isopentenyl pyrophosphate isomerase, and rubber transferase. The increase in these enzymic activities accounts in part for the chemical induction of rubber synthesis.
