Autor: Ben Lau, Francois Breton, Jyoti Prokash Nandy, Jianshun Zhang, Yong-Lai Feng, Yuqing Hou, Jiping Zhu
Publikováno v: Journal of Environmental Protection. :1519-1531
Understanding chemical transformations of contaminants and the resulting products is extremely important in devising proper monitoring methods for such contaminants and in assessing potential human exposure to the transformation products in the envir

Synthesis and conformation of proline containing tripeptides constrained with phenylalanine-like aziridine and dehydrophenylalanine residues
Autor: Shalini Shukla, Saibal Kumar Das, Amit Tewari, Jyoti Prokash Nandy, Erode N. Prabhakaran, Javed Iqbal
Publikováno v: Tetrahedron Letters. 43:6461-6466
Tripeptides containing proline and analogues of phenylalanine lead to the formation of β-turn structures. The synthesis and β-turn properties of four such compounds are discussed.

π-Facial selectivity in polyaniline supported cobalt catalysed aerobic epoxidation of N-cinnamoyl proline derivatives
Autor: Javed Iqbal, Jyoti Prokash Nandy, Erode N. Prabhakaran, Shalini Shukla
Publikováno v: Tetrahedron Letters. 42:333-337
Polyaniline supported cobalt salen catalyses the facially selective aerobic epoxidation (oxygen/2-methylpropanal) of N-cinnamoyl proline derived peptides. A high diastereoselectivity is observed for peptides which are able to adopt a γ- or β-turn d

Synthesis of a novel cis-proline-derived cyclic type VI beta-turn mimic via ring-closing metathesis
Autor: I. Nageshwar Rao, A. C. Kunwar, S. Kiran Kumar, Jyoti Prokash Nandy, Javed Iqbal, Anima Boruah
Publikováno v: The Journal of organic chemistry. 68(12)
A cis-proline derived cyclic mimic of a type VI beta-turn is synthesized via a ring-closing metathesis reaction. The solution NMR conformational study indicates that the major conformer of the cyclic peptide adopts a type VIa beta-turn in CDCl(3) and

Stereoselective synthesis of beta-substituted phenylalanine-beta-phenylisoserine-derived tripeptides using N-cinnamoyl-L-proline as template: synthesis of structural analogues of HIV protease inhibitors
Autor: Jyoti Prokash Nandy, Javed Iqbal, Shalini Shukla, Biswajit Saha, Iffat Siddiqui
Publikováno v: The Journal of organic chemistry. 67(22)
N-Cinnamoyl-L-proline can be used as a template on which beta-substituted phenylalanine and beta-phenylisoserine residues can be synthesized leading to tripeptide derivatives as structural analogues of HIV protease inhibitors.
