Caseinolytic protease P (ClpP) is considered as a promising target for the treatment of Staphylococcus aureus infections. In an unbiased screen of 2632 molecules, a peptidomimetic boronate, MLN9708, was found to be a potent suppressor of SaClpP function. A time-saving and cost-efficient strategy integrating in silico position scanning, multistep miniaturized synthesis, and bioactivity testing was deployed for optimization of this hit compound and led to fast exploration of structure-activity relationships. Five of 150 compounds from the miniaturized synthesis exhibited improved inhibitory activity. Compound 43Hf was the most active inhibitor and showed reversible covalent binding to SaClpP while did not destabilize the tetradecameric structure of SaClpP. The crystal structure of 43Hf-SaClpP complex provided mechanistic insight into the covalent binding mode of peptidomimetic boronate and SaClpP. Furthermore, 43Hf could bind endogenous ClpP in S. aureus cells and exhibited significant efficacy in attenuating S. aureus virulence in vitro and in vivo.

Objective: The aim of this study is to investigate the inhibitory effect of camptothecin derivative 3j on Non-Small Cell Lung Cancer (NSCLCs) cells and the potential anti-tumor mechanisms. Background: Camptothecin compounds are considered as the third largest natural drugs which are widely investigated in the world and they suffered restriction because of serious toxicity, such as hemorrhagic cystitis and bone marrow suppression. Methods: Using cell proliferation assay and S180 tumor mice model, a series of 20(S)-O-substituted benzoyl 7-ethylcamptothecin compounds were screened and evaluated the antitumor activities in vitro and in vivo. Camptothecin derivative 3j was selected for further study using flow cytometry in NSCLCs cells. Cell cycle related protein cyclin A2, CDK2, cyclin D and cyclin E were detected by Western Blot. Then, computer molecular docking was used to confirm the interaction between 3j and Topo L Also, DNA relaxation assay and alkaline cornet assay were used to investigate the mechanism of 3j on DNA damage. Results: Our results demonstrated that camptothecin derivative 3j showed a greater antitumor effect in eleven 20(S)-O-substituted benzoyl 7-ethylcamptothecin compounds in vitro and in vivo. The IC50 of 3j was 1.54 +/- 0.41 mu M lower than irinotecan with an IC50 of 13.86 +/- 0.80 mu M in NCI-H460 cell, which was reduced by 8 fold. In NCI-H1975 cell, the IC50 of 3j was 1.87 +/- 0.23 mu M lower than irinotecan (IC50 +/- SD, 5.35 +/- 0.38 mu M), dropped by 1.8 fold. Flow cytometry analysis revealed that 3j induced significant accumulation in a dose-dependent manner. After 24h of 3j (10 mu M)treatment, the percentage of NCI-H460 cell in S-phase significantly increased (to 93.54 +/- 4.4%) compared with control cells (31.67 +/- 3.4%). Similarly, the percentage of NCI-H1975 cell in S-phase significantly increased (to 83.99 +/- 2.4%) compared with control cells (34.45 +/- 3.9%) after treatment with 10 mu M of 3j. Moreover, increased levels of cyclin A2, CDK2, and decreased levels of cyclin D, cyclin E further confirmed that cell cycle arrest was induced by 3j. Furthermore, molecular docking studies suggested that 3j interacted with Topo I-DNA and DNA-relaxation assay simultaneously confirmed that 3j suppressed the activity of Topo I. Research on the mechanism showed that 3j exhibited anti-tumour activity via activating the DNA damage response pathway and suppressing the repair pathway in NSCLC cells. Conclusion: Novel camptothecin derivative 3j has been demonstrated as a promising antitumor agent and remains to be assessed in further studies.

The synthesis and use of oxetane modified dipeptide building blocks in solution and solid-phase peptide synthesis (SPPS) is reported. The preparation of building blocks containing non-glycine residues at the N-terminus in a stereochemically controlled manner is challenging. Here, a practical 4-step route to such building blocks is demonstrated, through the synthesis of dipeptides containing contiguous alanine residues. The incorporation of these new derivatives at specific sites along the backbone of an alanine-rich peptide sequence containing eighteen amino acids is demonstratedviasolid-phase peptide synthesis. Additionally, new methods to enable the incorporation of all 20 of the proteinogenic amino acids into such dipeptide building blocks are reported through modifications of the synthetic route (for Cys and Met) and by changes to the protecting group strategy (for His, Ser and Thr).

The development of a novel Z-scheme system with a high separation efficiency of the charge carriers for remarkably enhanced photocatalytic activity is highly desirable. Herein, a carbon quantum dot-modified SnNb2O6/BiOCl (CQD-SNO/BOC) Z-scheme system, in which the CQDs acted as a bridge for the charge carriers, was successfully synthesized. As expected, the CQDs acted as a bridge for the charge carriers that could separate and accumulate electrons from SnNb2O6 and holes from BiOCl by promoting the transfer of the photoinduced charge carriers, which enabled the BiOCl holes to maintain their high oxidation capability. Additionally, the CQDs not only endowed the SNO/BOC Z-scheme system with a large specific surface area that provided a greater number of active sites but also noticeably improved its visible light absorption capacity. Therefore, the CQDSNO/BOC Z-scheme system showed an improved photocatalytic performance for the degradation of benzocaine (BC), which was over 20 times, 10 times and 2 times greater than those of BiOCl, SnNb2O6 and SNO/BOC Z-scheme systems, respectively. In addition, the effects of catalyst concentration, pH value, different anions, and humic acid (HA) concentration on the photodegradation of BC were investigated in depth. Simultaneously, a four-stage pathway for the degradation of BC was proposed based on the degradation products that were identified, and the accuracy of this pathway was further verified based on biotoxicity assessments and toxicity predictions of the products. According to the ESR spectra and active species trapping experiments, a mechanism for the CQD-SNO/BOC Z-scheme system was proposed, in which the CQD bridge accelerated charge transfer. Based on these results, the CQD-modified Z-scheme system could be an efficient and promising photocatalyst for the degradation of PPCPs in water.
