This work summarizes select methodology of twin-screw melt granulation (TSMG) and process analytical technology that were used in the successful scaling-up and commercial transfer of high drug load (80.5% w/w) immediate release fevipiprant tablets.Th

P-glycoprotein (P-gp) is an important factor in the development of multidrug resistance (MDR) in cancer cells. In literature reports, a thieno[2,3-d]pyrimidine (QB13) was described as P-gp modulator and opposed effects on the cell accumulation of dis

The normal acid salt isopropylammonium tetrafluorohydrogenphthalate (3) was prepared and its structure was determined by X-ray crystallography. This salt is stabilized by N–H…O, O–H…O, C–H…O, and N–H…F hydrogen bonds. Compound 3 was c

The reactions of N-benzoyl-N'-(o-cyanoaryl)thioureas with ethyl bromoacetate under alkaline conditions led to the formation of either fused 2-(alkylsulfanyl)-4-aminopyrimidines or 2-(benzoylimino)-3-(o-cyanoaryl)thiazolidin-4-ones. The accurate appli

An anomalous acid salt ( 2 ) in the 2:1 ratio of tetrafluorophthalic acid and isopropylamine was prepared from bis(isopropylammonium) tetrafluorophthalate ( 1 ). Both salts were characterized by 13 C NMR spectroscopy in solution and in solid state, a

The reaction of isatoic anhydride (1) with carbon disulfide at room temperature unexpectedly afforded 1,2-dihydro-2-thioxo-4H-3,1-benzothiazin-4-one (2). The use of 13C-labeled carbon disulfide elucidated that CS2 was entirely incorporated into the p

We present a novel lead for inhibitors of multidrug resistance-associated proteins (MRPs). Compound 1 (4-[(5,6,7,8-tetrahydro-4-oxo-4H-[1]benzothieno[2,3-d][1,3]thiazin-2-yl)amino]benzoic acid) was about six times more potent than the known inhibitor

Caspases are proteolytic enzymes mainly involved in the induction and execution phases of apoptosis. This type of programmed cell death is an essential regulatory process required to maintain the integrity and homeostasis of multicellular organisms.

Acylureas (ureides) are valued for their important biological activities. Whereas cyclic acylureas have frequently been the object of solid-phase chemistry, only few reports have focused on the solid-supported preparation of acyclic representatives.
