Monobromoisophakellin, a New Bromopyrrole Alkaloid from the Caribbean Sponge Agelas sp.

In 2002 a high precision Austrian geoid has been computed by a combination of deflections of the vertical and gravity anomalies using least squares collocation ([7], [8]).. In

As nor different sextets nor their homologic items have any common denominators, the presentation of the sextet structure must proceed from examples. The inflection form is found 1)

In this work we report on the isolation and characterization of a new metabolite of a facultatively aerobic bacterium, isolated from the rumen of a Tunesian cow and iden- tified

Importantly in this case the new chloro- fullerene is formed in very small amounts and coelutes with several other unknown chlorofullerenes prevent- ing its easy separation

oxidative properties of the total extract and all compounds except for 10 and 11 were assessed using DPPH radical (Amarowicz et al., 2000) and TBARS (thiobarbituric acid

The pathways start from a 2-azido-4-alkynylimidazole which can be chemo- and stereoselectively reduced to the corresponding amino alkene using NaAlH 2 (OCH 2 CH 2 OMe) 2 (Red-Al)

As part of our program on the exploration of the biomimetic chemistry of the pyrrole-imidazole alkaloids [3], we report here the first synthesis of the natural product sventrin (1)
