Although cirrhosis is a key risk factor for the development of hepatocellular carcinoma (HCC), mounting evidence indicates that in subset patients presenting with non-alcoholic steatohepatitis (NASH) HCC manifests absence cirrhosis. Given sheer size ongoing fatty liver disease (NAFLD) epidemic and dismal prognosis associated late-stage primary cancer there an urgent need surveillance NASH population. Using serum levels biomarkers as vectors biopsy-proven or no outputs / binary classifier,...
A series of analogues featuring a 6-methoxy-1,2,3,4-tetrahydroisoquinolin-7-ol unit as the arylamine "head" group classical D3 antagonist core structure were synthesized and evaluated for affinity at dopamine D1, D2, receptors (D1R, D2R, D3R). The compounds generally displayed strong D3R with very good selectivity. Docking studies D2R crystal structures revealed that molecules are oriented such their units positioned in orthosteric binding pocket D3R, arylamide "tail" residing secondary...
Confined hydration and conformational flexibility are some of the challenges encountered for rational design selective antagonists G-protein coupled receptors. We present a set C3-substituted (-)-stepholidine derivatives as potent binders dopamine D3 receptor. The compounds characterized biochemically, well by computer modeling using novel molecular dynamics-based alchemical binding free energy approach which incorporates effect displacement enclosed water molecules from site. specific sites...
We evaluated C-3 alkoxylated and C-3/C-9 dialkoxylated (−)-stepholidine analogues to probe the tolerance at C-9 positions of tetrahydroprotoberberine (THPB) template toward affinity for dopamine receptors. A ethoxyl substituent appears optimal D1R since high affinities were observed compounds that contain an ethyl group C-9, with larger substituents tending decrease affinity. number novel ligands identified, such as 12a 12b, nanomolar no either D2R or D3R, compound being identified a...
Racemic and enantioselective synthesis of tetrahydroprotoberberine (THPB) alkaloids, a family natural products showing wide range biological activity, have been based either on extension or enhancement conventional methods new, recently developed tactics. Classical approaches to synthesize the THPB scaffold utilized Bischler-Napieralski cyclization/reduction Pictet-Spengler reactions generate benzyltetrahydroisoquinoline motif, followed by Mannich type condensation obtain tetracyclic core....
Caroli syndrome, characterized by saccular dilatation of intrahepatic ducts and congenital hepatic fibrosis, is without therapy in part due to its ultra-rare prevalence the apparent lack availability a suitable experimental model. While PCK rat has long been used as model fibropolycystic kidney disease, hepatobiliary biophysics this animal incompletely characterized. Compared age-matched, wild-type controls, demonstrated severe hepatomegaly large dilated ducts. Nevertheless, density was...
