      Conjugated lactam-steroid alkylators (LSA) have been shown to exhibit superior activity at controlling cancer models and overlap drug resistance to conventional chemjournalapy. LSA produce anticancer activity through dual action by combining the direct induction of cellular DNA damage with the inhibition of PARP activity and consecutive DNA repair activity, as well as modulating PARP1/2 mRNA transcription. BRCA1-mutated UWB1.289 ovarian cancer cells with defective PARP-oriented repair mechanism show significantly higher sensitivity to these agents.

      In this study, rhein-SLNs were successfully produced by hot homogenization followed by ultrasonication. Precirol ATO5 in which rhein exhibited higher partition coefficient was selected for preparation of SLNs. In the dynamic light scattering, the rhein SLNs showed a smaller size with a mean value of 120.8 ± 7.9 nm and with zeta potential of −16.9 ± 2.3 mV. SLNs exhibited a good stability during the period of 2 months. The SLNs indicated faster drug release with a burst release within 2 hr and followed by a sustained release with a biphasic drug-release pattern. Comparing with the same concentration (free drug), the cellular cytotoxicity of rhein-loaded SLNs increased significantly at the same incubation condition. In vivo, the AUC0-t of rhein in the form of SLNs was significantly increased and was 2.06-fold that of suspensions group. The results showed an increased oral absorption and improved the oral bioavailability of rhein by the formulation of SLNs.

      In this study, we performed virtual screening of ZINC natural compounds by docking to the Abl kinase ATP-binding site using Glide software. Two natural inhibitors ZINC08764498 (hit1) and ZINC12891610 (hit2) were selected by considering their high Glide docking score and stable interaction with the hinge region residue Met-318 of Abl kinase catalytic domain. The compounds were further validated using density functional theory and 10-ns molecular dynamic simulations. In vitro testing results showed that compound ZINC08764498 (hit1) has selective pro-apoptotic activity on Bcr-Abl-overexpressing K-562 cells and no significant cytotoxicity on Bcr-Abl-negative HEK-293 cell line.

      Thumbnail image of graphical abstract

      To improve the stability of the natural antimicrobial peptide CPF-C1, a series of analogs were designed and synthesized by chemical modification. Among the analogs, CPF-9 was notable due to its greater antimicrobial potency in vitro and in vivo and its superior stability, lower hemolytic activity, and higher antibiofilm activity. It killed bacteria not only by disrupting the bacterial membranes but also by binding to DNA. This analog is a potential antibiotic candidate for treating infections induced by multidrug-resistant bacteria.

      The phloroglucinol derivative of Hypericum species, isoaustrobrasilol B, was active against T. vaginalis. It significantly inhibited NTPDase and ecto-5′-nucleotidase activities, and the influence of extracellular nucleotide accumulation on immune mechanisms was evaluated revealing enhanced IL-8 levels in T. vaginalis-stimulated neutrophils. The associative effect of trophozoites death and ectonucleotidases modulation by isoaustrobrasilol B may increase the susceptibility of T. vaginalis to neutrophils consequently, contributing to parasite clearance.

      Large conformational changes were detected in hAgo2-free system comparing to RNA bounded hAgo2, especially for PAZ domain. The reorientation of PAZ domain not only influences the binding of helix-7 and RNA duplex, the initial pairing process, but also the shape of N-PAZ cleft, where the supplemental base pairing occurs. We speculate that PAZ domain played important role in hAgo2-mediated miRNA-induced gene regulation.

      The human apurinic/apyrimidinic endonuclease 1 (APE1) is a multifunctional DNA repair enzyme with relevant redox signalling functions. The quinone derivative E3330, a redox inhibitor of APE1, decreased the colony formation and chemoinvasion of docetaxel-treated MDA-MB-231 cells (represented in blue). In addition, E3330 as single agent (represented in red) significantly reduced the collective cell migration. These results suggest APE1 redox function as a potential target for the modulation of cell migration and invasion in metastatic breast cancer.

      99mTc-kanamycin, used for bacterial infection imaging, is short-lived and cannot be transported over long distances. To resolve this, kanamycin was labeled with lutetium-177, a long-lived isotope that emits β- and γ-radiation. Radiolabeling of 177Lu-kanamycin was optimized. 177Lu-kanamycin was prepared with a very high yield (~100%) and showed excellent stability in vitro. Biodistribution and scintigraphy studies in mice and rabbit showed rapid clearance from body, suggesting that 177Lu-kanamycin could be used for medical imaging.

      Application of anticancer peptides is limited by fast elimination from the systemic circulation. In this study, chitosan nanoparticles are used for the controlled release of an engineered antiangiogenic peptide derived from the N-terminal fragment of human endostatin. The nanoparticles were characterized before and after peptide loading by FTIR, zeta sizer and SEM. Our measurements revealed that chitosan nanoparticles are able to adsorb the peptide as ~70% and complete release took place after 80 h. According to in vitro studies, the loaded peptide was much more toxic for endothelial cells than cancer cell lines. These results underscore the promise of chitosan nanoparticles as therapeutics nanosystems.

      In silico analysis and screening of the nsSNPs present in the DNA-binding domain (homeobox) of human HOXB13 gene is of crucial importance, since nsSNPs are known to be the prime cause for hereditary prostate cancer. Further, in silico protein mutation studies and subsequent validation by Ramachandran plot revealed P222R, G216C, W263R, and K218R to render serious damaging effects on the HOXB13 protein structure, stability, and function. However, the exact mechanism and pathology of these nsSNPs should be studied in depth in vitro/ in vivo.

      NMR spectroscopy was used to determine the structure of Staphylococcus aureus sortase A transpeptidase enzyme in complex with a pyridazinone-based small molecule, a potential anti-infective agent. Computational and synthetic chemistry methods led to second-generation analogs that are 70-fold more potent than the lead molecule, less cytotoxic and effective at impairing sortase A-mediated protein display on the surface of S. aureus. These pyridazinone analogues are attractive candidates for further development into anti-infective agents.

      Benzotriazepine bromodomain 4 inhibitors capable of inhibiting osteoclast differentiation without cytotoxic effects on murine RAW264.7 osteoclast progenitors, as well as human CD14+ monocytes, were in silico designed and synthesized. This study demonstrates that in silico docking and molecular dynamics simulations are useful to identify BRD inhibitors with a particular selectivity profile. Furthermore, the compounds identified in this study have remarkable antiosteoclastogenic potential and warrant further studies for drug development against bone loss diseases characterized by excessive osteoclast activity.

      Two novel peptides (brevinin1 HYba1 and brevinin1 HYba2) were identified from the skin secretion of the frog Hydrophylax bahuvistara. Amidation proved to be a favorable modification, which enhanced the biological activity of the brevinin1 peptides without affecting its low hemolytic property. These peptides also showed very high cytotoxicity toward Hep 3B cancer cell lines.

      A series of novel 1,8-naphthyridine derivatives variously modified were synthesized and their β-AR blocking activities were determined. Preliminary evidence suggests that the inhibitory effects of the newly synthesized 1,8-naphthyridine analogues 3 and 10 on either alprenolol or isoprenaline-induced lipolysis in rat fat cells may result from inhibition of the low-affinity β3-adrenoceptor.

      “Biofocussed chemoprospecting” represents a hybrid of bioprospecting and a scaffold-based approach and includes property filtering to optimize qualities such as diversity, drug likeness, ease of synthesis, low cost and “bio likeness.” To demonstrate this approach, we generated two dipeptide-based libraries, first as large virtual libraries, followed by focussed synthesis. The resultant libraries demonstrated a hit rate comparable to target-based approaches, with additional potential to identify new targets and mechanisms.

      Compounds showing dual anticancer/anti-inflammatory activity are of increasing interest for the treatment of cancer due to the implication of inflammatory mechanisms in most malignancies. This spurred the synthesis of compounds containing a purine character (a scaffold for anticancer drugs) together with a pyrazole moiety (a scaffold for anti-inflammatory agents). Among these compounds, 10b was the most active against all used cell lines.

      θ-defensins are cyclic, host defence peptides with strong antimicrobial activity. In the current study, we aimed to define anticancer potential of θ-defensin analogues. Their serine-containing derivatives were more cytotoxic against breast cancer cells (SKBR3, MDA-MB-231) than against mammary epithelial cells (HB2). Analogues also enhanced the effect of cisplatin and doxorubicin hydrochloride on triple-negative breast cancer cell line (MDA-MB-231).

      β-Tubulin isotypes are attractive therapeutic targets for the design of specific anticancer treatments. Herein, we carried out docking and molecular dynamics simulations to determine the binding mode of a series of benzimidazole-2-carbamete derivatives in the βI-, βIII-, and βVI-tubulin isotypes. Finally, we propose novel approaches in the design of BzCs as microtubule polymerization inhibitors with a potential higher affinity to βI and βIII isotypes compared to that to the βVI isotype.
