Adriaan J. Minnaard and Ben L. Feringa of the University of Groningen devised (J. Azido-PEG2-CH2COOH Price Am. Chem. Soc. 2010, 132, 14349. DOI: 10.1021/ja105704m) what promises to be a general…
(+)-Subincanadine F (Li), (±)-Strychnine (Reissig), (-)-Virginiamycin M2 (Panek) Aldehydes such as 1 are readily available by direct enantioselective chlorination. Robert Britton of Simon Fraser University found (Org. Lett. 2010, 12,…
Asymmetric epoxidation of a prochiral alkene is an appealing process because two stereogenic centers are established in the course of the reaction. Often, the starting alkene is inexpensive. 1203499-17-5 Order…
The complex polycyclic structure of N-Methylwelwitindolinone D Isonitrile (3) was assigned in 1999. The welwitinines show an intriguing range of biological activity, including reversal of P-glycoprotein-mediated multidrug resistance in human…
The periwinkle-derived alkaloids vinblastine (2a) and vincristine (2b) are still mainstays of cancer chemotherapy. The more complex half of these dimeric alkaloids, vindoline (1), presents a formidable challenge for total…
The Hajos-Parrish cyclization was a landmark in the asymmetric construction of polycarbocyclic natural products. PMID:24220671 Impressive at the time, the proline-mediated intramolecular aldol condensation proceeded with an ee that was…
Nt bone marrow-derived cells inside the development of atherosclerosis within this model . In contrast, transplantation of bone marrow from Tlr42/2 mice into Ldlr2/2 recipients, followed by feeding a high-cholesterol,…
Nhibitor II (40 nM); or MAPK inhibitor PD98059 (50 lM) for 1 hour at 378C. HCEC chemotaxis was measured in response to the buffer control (0.1 BSA in Gey’s buffer);…
Maoecrystal V (3), isolated from the Chinese medicinal herb Isodon eriocalyx, shows selective inhibition of HeLa cells at low nanomolar concentration (IC50 = 60 nm). 6-(Diphenylphosphino)-2,2′-bipyridine In stock Chuang-Chuang Li…
