Patients with osteoporosis and joint disabilities represent a constant growing and challenging population to be treated in the musculoskeletal clinical field. Especially in the case of total hip arthroplasty, new solutions should be developed to compensate ...
The marcfortine alkaloids are complex indolic secondary metabolites isolated from various Penicillium sp. and are potent anthelmintic agents. Herein, we report the first total synthesis of marcfortine B (I). The key features of our synthesis are the use of ...
An asym. synthesis of an orthogonally protected gamma -carboxy-L-glutamic acid (L-Gla) is developed featuring a key proline-catalyzed Knoevenagel condensation between Garner's aldehyde and Meldrum's acid. [on SciFinder (R)] ...
TGR5, a metabotropic receptor that is G-protein-coupled to the induction of adenylate cyclase, has been recognized as the molecular link connecting bile acids to the control of energy and glucose homeostasis. With the aim of disclosing novel selective modu ...
This study investigated the oxidation of the oral contraceptive 17alpha-ethinylestradiol (EE2) during ozonation. First, the effect of ozone (O-3) on the estrogenic activity of aqueous solutions of EE2 was studied using a yeast estrogen screen (YES). It cou ...
The reductive cleavage of Me vinyl-b-ionyl ether or the deprotonation of 3,2',6',6'-tetramethyl-5-(1-cyclohexenyl)-1,3-pentadiene gives rise to an organometallic C15 species that combines selectively with a variety of electrophiles at the terminal chain po ...
An efficient synthesis of functionalized 3-alkyl-3-cyanomethyl-2-oxindole by a palladium-catalyzed domino Heck-cyanation reaction has been developed. Reaction of ortho-iodoanilide with potassium ferro(II)cyanide in the presence of palladium acetate and sod ...
A concise synthesis of a highly functionalized, orthogonally protected amino triol I (R = CH2Ph, R1 = SiPh2CMe3) was achieved via a Mannich reaction between a corresponding phenol II and a chiral oxazinone III as a key step. The utility of such an approach ...
Highly efficient capillary electrochromatog. sepns. of cardiac glycosides and other steroids are presented. Employing butyl-derivatized silica particles as stationary phase resulted in a nearly three times faster electroosmotic flow (EOF) compared to capil ...
The resistance mechanism of vetiver (Chrysopogon zizanioides) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazinerely on hydroxylation mediated by b ...
