Journal ArticleDOI
Identification of a compound isolated from German chamomile (Matricaria chamomilla) with dermal sensitization potential.
TL;DR: Three candidate sensitizers were isolated from German chamomile based on activity‐guided fractionation of chammile extracts tested using the in vitro KeratinoSens™ assay, finding the polyacetylene tonghaosu to be unstable and categorized as potential pre‐hapten.
Journal ArticleDOI
One-step, stereoselective synthesis of octahydrochromanes via the Prins reaction and their cannabinoid activities.
Shuneize Slater,Pradeep B. Lasonkar,Saqlain Haider,Moneerah J. Alqahtani,Amar G. Chittiboyina,Ikhlas A. Khan +5 more
TL;DR: A total of 10 compounds were synthesized by altering the enantiomer of isopulegol and the substituted benzaldehyde, and the resulting enantiopure octahydrochromenes were screened in vitro against the cannabinoid receptor isoforms CB1 and CB2.
Journal ArticleDOI
Identification and quantification of 1,3-dimethylbutylamine (DMBA) from Camellia sinensis tea leaves and dietary supplements.
Bharathi Avula,Mei Wang,S Sagi,Pieter A. Cohen,Pieter A. Cohen,Yan-Hong Wang,Pradeep B. Lasonkar,Amar G. Chittiboyina,Wei Feng,Ikhlas A. Khan,Ikhlas A. Khan +10 more
TL;DR: The presence of DMBA was confirmed using a reference standard and was not detected in any of 25 authentic or commercial samples of Camellia sinensis tea leaves (green tea, black tea, Oolong tea, and Pouchung tea).
Journal ArticleDOI
Synthesis of 3-Azidopiperidine Skeleton Employing Ceric Ammonium Nitrate (CAN)-Mediated Regioselective Azidoalkoxylation of Enol Ether: Total Synthesis of D2 Receptor Agonist (±)-Quinagolide
Subhash P. Chavan,Subhash P. Chavan,Appasaheb L. Kadam,Appasaheb L. Kadam,Pradeep B. Lasonkar,Rajesh G. Gonnade,Rajesh G. Gonnade +6 more
TL;DR: The PPTS-catalyzed intramolecular diastereoselective Henry reaction to fix three contiguous stereocenters on tetrahydronaphthalene and the first-of-its-kind synthesis of the 3-azidopiperidine skeleton, using a CAN-mediated regioselectives azidoalkoxylation of enol ether, are important findings of the present work.
Journal ArticleDOI
A novel and enantioselective synthesis of d-(+)-biotin via a Sharpless asymmetric dihydroxylation strategy
TL;DR: In this paper, a novel and enantioselective synthesis of d -(+)-biotin has been achieved starting from commercially available cyclohexanone using Sharpless asymmetric dihydroxylation of a (E )-ethyl 3-(2-chlorocyclohex-1-en-1yl)acrylate derivative.
