Late intermediates in the biosynthesis of narciclasine

Journal of the Chemical Society D: Chemical Communications, 1971
Tracer experiments show the intermediacy of racemic noroxomaritidine (5), normaritidine (7), and crinine (4) in the biological conversion of O-methylnorbelladine (1) into narciclasine (11).

Spinal Cord Dynorphin Precursor Intermediates Decline During Late Gestation

Journal of Neurochemistry, 1995
Abstract: This laboratory has previously reported that the maternal opioid analgesia associated with pregnancy and parturition is mediated, at least in part, by a maternal spinal cord dynorphin/κ opioid system. This analgesia is accompanied by an increase in dynorphin peptides (1–17 and 1–8) in the lumbar spinal cord.

Intermediate-band photometry of late-type stars.

Publications of the Astronomical Society of the Pacific, 1976
In four-color, intermediate-band photometry of late-type stars, difficulty has been experienced in reproducing the Str5mgren system as defined by standard stars published by Crawford and Barnes. The difficulty is believed to be connected with the fact that an international, bulk order for filters has produced a considerably narrower V filter than that ...

Total synthesis of LewisX using a late-stage crystalline intermediate

Carbohydrate Research, 2015
Herein, we report on a highly efficient synthesis of a crystalline protected Lewis(X) trisaccharide that was converted to Lewis(X) following global deprotection. The trisaccharide was prepared in a highly convergent synthesis (seven steps, longest linear sequence) and in a 38% overall yield using a strategy that involved the regioselective ...
