Diastereoselective synthesis and biological evaluation of enantiomerically pure tricyclic indolines
He,Griffiths,Wang,Wang
supporting information, p. 4241 - 4245 (2017/07/10)
Tricyclic indolines are common in both natural products and synthetic chemical probes. In this study we demonstrated that enantiomerically pure tricyclic indolines can be prepared from an inexpensive commercially available chiral starting material, pyroglutamic acid. The synthesis features a highly diastereoselective gold-catalyzed cyclization of alkyne-tethered indoles and subsequent diastereoselective reductive ring-opening reaction. Using this approach, we synthesized analogs of our previously discovered tricyclic indoline probes that possess antibacterial and resistance-modifying activity. The biological activity against methicillin-resistant Staphylococcus aureus (MRSA) of these analogues was evaluated and reported. The synthetic approach reported may be leveraged in the future to prepare diastereopure chemical probes for the determination of biological targets for drug discovery.
CYCLIC AMINE DERIVATIVES AS EP4 RECEPTOR ANTAGONISTS
-
Paragraph 0410; 0411; 0412, (2015/03/31)
There is described a novel group of cyclic amine derivative compounds, having an EP4 receptor antagonistic activity and specifically pharmaceutical compounds which are useful for the treatment or alleviation of Prostaglandin E mediated diseases. The present invention therefore relates to novel compounds which are selective antagonists of the EP4 subtype of PGE2 receptors with analgesic and antinflammatory activity, processes for their preparation, pharmaceutical compositions containing them and their use as medicaments, inter alia for the treatment or alleviation of Prostaglandin E mediated diseases such as acute and chronic pain, osteoarthritis, inflammation-associated disorder as arthritis, rheumatoid arthritis, cancer, migraine and endometriosis.

Ibrahim, Mohamed A.,Johnson, Henry W. B.,Jeong, Joon Won,Lewis, Gary L.,Shi, Xian,Noguchi, Robin T.,Williams, Matthew,Leahy, James W.,Nuss, John M.,Woolfrey, John,Banica, Monica,Bentzien, Frauke,Chou, Yu-Chien,Gibson, Anna,Heald, Nathan,Lamb, Peter,Mattheakis, Larry,Matthews, David,Shipway, Aaron,Wu, Xiang,Zhang, Wentao,Zhou, Sihong,Shankar, Geetha
experimental part, p. 1368 - 1381 (2012/04/04)
A series of subtype selective sphingosine 1-phosphate receptor 1 (S1P 1) antagonists are disclosed. Our high-throughput screening campaign revealed hit 1 for which an increase in potency and mouse oral exposure was achieved with minor modifications to the chemical scaffold. In vivo efficacy revealed that at high doses compounds 12 and 15 inhibited tumor growth. Further optimization of our lead series led to the discovery of proline derivatives 37 (XL541) and 38 which had similar efficacy as our first generation analogues at significantly lower doses. Analogue 37 displayed excellent pharmacokinetics and oral exposure in multiple species.

scheme or table, p. 5574 - 5583 (2011/10/02)
l- And d-glutamic acids, as well as trans-4-hydroxy-l-proline, are converted to the corresponding 3-guaninyl-5-hydroxymethyl-2-pyrrolidinone (4) or 3-adeninyl-5-hydroxymethyl-2-pyrrolidinone (5) nucleoside analog. The protecting group used to block the lactam nitrogen in key intermediates has a significant effect on the diastereoselectivity of the coupling reaction with adenine or guanine.
