Abstract
Hybrid organic-inorganic bio-inspired apatite nanoparticles (NPs) are attractive for biomedical applications and especially in nanomedicine. Unfortunately, their applications in nanomedicine are limited by their broad particle size distributions and uncontrolled drug loading due to their multistep synthesis process. Besides, very few attempts at exposing bioactive peptides on apatite NPs are made. In this work, an original one-pot synthesis of well-defined bioactive hybrid NPs composed of a mineral core of bioinspired apatite surrounded by an organic corona of bioactive peptides is reported. Dual stabilizing-bioactive agents, phosphonated polyethylene glycol-peptide conjugates, are prepared and directly used during apatite precipitation i) to form the organic corona during apatite precipitation, driving the size and shape of resulting hybrid NPs with colloidal stabilization and ii) to expose peptide moieties (RGD or YIGSR sequences) at the NPs periphery in view of conferring additional surface properties to enhance their interaction with cells. Here, the success of this approach is demonstrated, the functionalized NPs are fully characterized by Fourier-transform infrared, Raman, X-ray diffraction, solid and liquid state NMR, transmission electron microscopy, and dynamic light scattering, and their interaction with fibroblast cells is followed, unveiling a synergistic proliferative effect.

Abstract
A simple phosgene- and halogen-free method for synthesizing α-amino acid N-carboxyanhydrides (NCAs) is described. The reaction between Boc-protected α-amino acids and T3P reagent gave the corresponding NCA derivatives in good yield and purity with no detectable epimerization. The process is safe, is easy-to-operate, and does not require any specific installation. It generates nontoxic, easy to remove byproducts. It can apply to the preparation of NCAs for the on-demand on-site production of either little or large quantities.

Design, synthesis and biological evaluation of novel 2,4-bismorpholinothieno[3,2-d]pyrimidine and 2-morpholinothieno[3,2-d]pyrimidinone derivatives as potent antitumor agents. Bioorg Chem 2020; 99:103796.

Abstract
To develop novel therapeutic agents with anticancer activities, two series of novel 2,4-bismorpholinyl-thieno[3,2-d]pyrimidine and 2-morpholinothieno[3,2-d]pyrimidinone derivatives were designed, synthesized and evaluated for their biological activities. Among them, compound A12 showed the most potent antitumor activities against HCT116, PC-3, MCF-7, A549 and MDA-MB-231 cell lines with IC50 values of 3.24 μM, 14.37 μM, 7.39 μM, 7.10 μM, and 16.85 μM, respectively. Further explorations in bioactivity were conducted to clarify the anticancer mechanism of compound A12. The results showed that compound A12 obviously inhibited the proliferation of A549 cell lines and decreased mitochondrial membrane potential, which led to the apoptosis of cancer cells and suppressed the migration of tumor cells.
