Abstract(3‐(3‐Bromo‐4‐hydroxy‐S‐methoxy‐phenyl)alanine (Ie) exerts a long‐acting antihypertensive effect in rats and dogs : its synthesis and its optical resolution have already appeared in the literature. 1 Ten new mono‐ and polybrominated phenylalanines with hydroxy‐ and/or methoxy‐groups are here described. These unnatural amino‐acide were synthesized by direct bromination, or via the acetamidomalonic esters (V), or via the azlactones (VI) and the corresponding phenylpyruvic acids (VIII).

A series of novel carbohydrate-modified antitumor compounds were designedbased on glucose transporter 1 (GLUT1), and evaluated for their anticancer activities against four cancer cell lines. The ribose derivatives (compound 9 and 10) exhibited modest inhibitory activity. The compound 9 significantly inhibited the migration of A549 cell and induced A549 cell apoptosis in a concentration-dependent manner
