Tribological Properties of Alkylphenyl Diphosphates as High-Performance Antiwear Additive in Lithium Complex Grease and Polyurea Grease for Steel/Steel Contacts at Elevated Temperature

, 2016
The alkylphenyl diphosphates pentaerythritol tetrakis­(diphenyl phosphate) (PDP) and trimethylolpropane tris­(diphenyl phosphate) (TDP) were evaluated as the antiwear additives in lithium complex grease and polyurea grease at 200 °C.

The 8-MOP identification and isolation from the plant material and percutaneous permeation in the modified Flynn’s cell

Current Issues in Pharmacy and Medical Sciences
Xanthotoxin (8-methoxypsoralen, methoxsalen) is a natural furanocoumarin consisting of coumarin annulated with furan. It’s biosynthetic route in plants continues with the activation of dimethylallylpyrophosphate (DMAPP), produced via the mevalonate ...

A prebiotic basis for ATP as the universal energy currency

PLoS Biology, 2022
ATP is universally conserved as the principal energy currency in cells, driving metabolism through phosphorylation and condensation reactions. Such deep conservation suggests that ATP arose at an early stage of biochemical evolution. Yet purine synthesis

Nanopore-Based Identification of Individual Nucleotides for Direct RNA Sequencing

, 2016
We describe a label-free ribobase identification method, which uses ionic current measurement to resolve ribonucleoside monophosphates or diphosphates in α-hemolysin protein nanopores containing amino-cyclodextrin adapters.

Inhibition of Geranylgeranyl Diphosphate Synthase by Bisphosphonates and Diphosphates:  A Potential Route to New Bone Antiresorption and Antiparasitic Agents

, 2016
We report the inhibition of a human recombinant geranylgeranyl diphosphate synthase (GGPPSase) by 23 bisphosphonates and six azaprenyl diphosphates. The IC50 values range from 140 nM to 690 μM. None of the nitrogen-containing bisphosphonates that inhibit
