Substituted phenanthrenes with basic amino side chains: a new series of anti-breast cancer agents.
- Shagufta, A. Srivastava, +4 authors G. Panda
- Chemistry, MedicineBioorganic & medicinal chemistry
- 1 March 2006
One of the compounds synthesized showed anti-breast cancer activity in 7,12-dimethylbenz[a]anthracene (DMBA) induced hormone-dependent mammary tumor in rat and the activity was comparable to that shown by tamoxifen.
Naphthalimide derivatives with therapeutic characteristics: a patent review

The membranous layer is present in whole of the anterior abdominal wall and it divides the superficial fascia into three layers: superficial fatty layer, intermediate membran Mous layer, and deep fatty layer.
In the title compound, C13H17N3O3S·0.5H2O, the morpholine ring adopts a chair conformation. The conformation of the molecule is stabilized by intramolecular N—H⋯O and N—H⋯S hydrogen bonds.…
Identification of novel β-lactams and pyrrolidinone derivatives as selective Histamine-3 receptor (H3R) modulators as possible anti-obesity agents.

- Chemistry, MedicineACS combinatorial science
- 26 September 2016
The photocatalytic method was found to be effective for the condensation of less reactive heterocyclic aldehydes with o-phenylenediamines and was successfully employed for accessing pharmaceutically important benzimidazoles.
Synthesis of Alkaloid-Mimicking Tricyclic Skeletons by Diastereo- and Regioselective Ugi/ipso-Cyclization/Aza-Michael Cascade Reaction in One-Pot.

- 23 February 2016
A one-pot process has been developed for preparing alkaloid-like tricyclic skeletons by employing an Ugi reaction, an acid mediated ipso-cyclization and an aza-Michael addition. The transformation is…
A synthetic route to highly substituted 1,2,3,4-tetrahydroisoquinolines via Yb(OTf)3 -catalyzed diastereoselective ring opening of bridged oxazolidines: asymmetric synthesis of 2-azapodophyllotoxin.
A robust and efficient synthetic route to highly functionalized enantiopure 1,2,3,4-tetrahydroisoquinolines (THIQs) from Garner aldehyde is reported and the enantioselective synthesis of 2-azapodophyllotoxin was achieved with an overall yield of 35.4% using this synthetic route.
