De Novo Design of Boron-Based Peptidomimetics as Potent Inhibitors of Human ClpP in the Presence of Human ClpX
Boronic acids have attracted the attention of synthetic and medicinal chemists due to boron's ability to modulate enzyme function. Recently, we demonstrated that boron-containing amphoteric building blocks facilitate the discovery of bioactive aminoboronic acids. Herein, we have augmented this capability with a de novo library design and a virtual screening platform modified for covalent ligands. This technique has allowed us to rapidly design and identify a series of α-aminoboronic acids as the first inhibitors of human ClpXP, which is responsible for the degradation of misfolded proteins.

Preparation of (1R)-(S)-pinane diol-1-amino-3-methyl-butane-1-borate and a salt thereof
The invention discloses a method for preparing (1R)-(S)-pinanediol-1-amino-3-methylbutane-1-borate ester and a salt thereof. The method for preparing (1R)-(S)-pinanediol-1-amino-3-methylbutane-1-borate ester comprises step A and step B in the following synthetic route, wherein in the formula, X represents a halogen atom and M represents an alkali metal. (1R)-(S)-pinanediol-1-amino-3-methylbutane-1-borate ester is subjected to a salt forming reaction with an organic acid or an inorganic aid, and an acidic salt of (1R)-(S)-pinanediol-1-amino-3-methylbutane-1-borate ester is obtained. The method of the invention can help to synthesize high-purity bortezomib or other boropeptide compounds in low cost, is accord with industrial production requirements and has practical value.

Design, synthesis and biological evaluation of novel analogs of bortezomib
Novel analogs of bortezomib were designed, synthesized and in vitro biological evaluation was carried out using human tumor cell lines A549 and PC3. Docking studies of these analogs of bortezomib was discussed. According to biological investigations, the inhibitors 4, 6, and 8 were found to be more potent than reference drug candidate bortezomib. A549 cell line showed significant sensitivity towards 4, 6, and 8 with IC50 values 14.03, 18.5, and 12.4 nM, respectively, and PC3 cell line showed IC50 values 26.1, 37.0, and 21.2 nM, respectively. The IC50 values of bortezomib in these cell lines are 27.3 nM and 42.0 nM. Copyright
