A series of diamine and polyamine derivatives, either free amines or salts (HCl or TFA), of aspartic and glutamic acid were prepared in excellent yields using Rink Amide solid-phase synthesis. The asparagine and glutamine derivatives were all evaluated for their ability to inhibit Tat-TAR binding using a FIGS cellular assay, with the polyamine derivatives exhibiting the most promising binding activity
The invention relates to compounds, compositions, kits, and methods for the treatment of a cancer. In particular, the invention relates to compounds, compositions, or kits comprising a folate-vinca conjugate, and methods for the treatment of a cancer with a folate-vinca conjugate.
Herein, we report an efficient photoinduced iron-catalyzed strategy for cross-couplings of alkyl carboxylic and acrylic acids, which provides a powerful tool for the synthesis of a variety of alkenes with polar functional groups. This novel synthetic methodology can also be applied to the preparation of ketones by using α-keto acids. Mechanistic experiments revealed preliminary mechanistic details
