Title: Pentacyclic Triterpenoidal Derivatives
Inventor: AHMED NAGLAH
Filed: 2018-09-17
Abstract: A pentacyclic triterpenoidal derivative can include 3, ll-dioxo-24(phenyl)-urs-12-en- 24-one (4), 24-norurs-12-en-24(phenyl)-3,11-dione (5), 3,11-dioxo-24(Phenyl)-urs-1,12- diene-24-one (6), or 24-nor-urs-1,12-diene-24(phenyl)-3,11-dione (7). The pentacyclic triterpenoidal derivative deomonstrates highly potent 5-lipoxygenase inhibition activity.

Title: Method of scavenging hydrogen sulfide and/or sulfhydryl compounds
Inventor: JANAK KEVIN EDWARD
Filed: 2015-02-18
Abstract: A method of reducing the amount of sulfhydryl compounds from sour hydrocarbon fluids is described. In the method, an aldehyde-releasing compound, which is high temperature stable and is highly water-soluble, is introduced to a hydrocarbon fluid stream as a scavenger for sulfhydryl compounds. The aldehyde-releasing compound is allowed to mix with the hydrocarbon fluid stream and the aldehyde-releasing compound is allowed to react with the sulfhydryl compounds present in the hydrocarbon fluid stream, thereby reducing the presence sulfhydryl compound in the hydrocarbon fluid stream.
