734 results about "Phenacyl" patented technology

In organic chemistry, a phenacyl group is an aromatic substituent that consists of a phenyl group attached to an acyl group. A molecule containing a phenacyl group has the formula RCH₂(CO)C₆H₅ and the structure shown to the right. Here, R denotes the remainder of the molecule; for instance, if R is Br, then the compound could be called "phenacyl bromide". Note however that in the standard IUPAC nomenclature this compound would instead be called "2-bromo-1-phenylethanone".

Companion diagnostic assays for cancer therapy

A method for classifying cancer patients as eligible to receive cancer therapy with a small molecule inhibitor of Bcl-2 comprising determination of the presence or absence in a patient tissue sample of chromosomal copy number status at the chromosomal locus 13q14 comprising the microRNA's miR-15a and miR-16-1 or at the chromosomal locus 11q23.1 comprising the microRNA miR-34c. The classification of cancer patients based upon the presence or absence of 13q14 loss or gain allows better selection of patients to receive chemotherapy with a small molecule Bcl-2 inhibitor such as N-(4-(4-((2-(4-chlorophenyl)-5,5-dimethyl-1-cyclohex-1-en-1-yl) methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(morpholin-4-yl)-1-((phenylsulfanyl) methyl)propyl)amino)-3-((trifluoromethyl)sulfonyl)benzenesulfonamide, and for monitoring patient response to this therapy.
