A scalable and convergent synthesis of a BTK (Bruton’s tyrosine kinase) inhibitor has been developed. Synthetic routes to key intermediates were explored for the scale-up campaign, especially the process for 6-dimethylaminodihydroisoquinolinone, wh

BACKGROUND: Ursolic acid and its cis- and trans-3-O-p-hydroxycinnamoyl esters have been identified as constituents of American cranberries (Vaccinium macrocarpon), which inhibit tumor cell proliferation. Since the compounds may contribute to berry an

An efficient synthesis of an adrenoceptor antagonist has been developed and demonstrated in a pilot plant. A linear synthesis that relied on a catalytic reduction of a rather insoluble nitroaromatic proved to be a viable route. The active pharmaceuti

During the development of a sodium borohydride mediated reductive amination of 3-nitrobenzaldehyde with methylamine, studies revealed that partial reduction of the nitro group occurred, and potentially dangerous azo- and azoxy-containing products wer

Regulation of the matrix metalloproteinases (MMPs), the major mediators of extracellular matrix (ECM) degradation, is crucial to regulate ECM proteolysis, which is important in metastasis. This study examined the effects of 3 flavonoid-enriched fract

Proanthocyanidin-rich extracts were prepared by fractionation of the fruit of the North American cranberry (Vaccinium macrocarpon). In vitro growth inhibition assays in eight tumor cell lines showed that selected fractions inhibited the growth of H46

A synthetic route to a potent and selective α-1-adrenergic receptor antagonist has been developed and demonstrated in a pilot plant. The route has been used in two pilot plant campaigns and has produced RO3203546 in 2.3 and 12.0 kg batch sizes. The

The disilylphosphido complexes M[P(SiPh 3 ) 2 ] 2 , where M=Zn, Cd, Hg, and Sn, are prepared in 50-90% yields and isolated as crystalline solids or powders. Cryoscopic and NMR data indicate that the compounds are monomers in solution. The solid-state

Several homoleptic disilylphosphido complexes are described, which are relatives of the well-known homoleptic disilylamido complexes. The differing properties of the amido and phosphido ligands are ascribed to normal periodic relationships.
