Abstract
This study reports the design and synthesis of novel dialkyl (4-amino-5H-chromeno[2,3-d]pyrimidin-5-yl)phosphonates as potential antitumor agents against A549 (lung cancer), DU-145 (prostate cancer), PC-3 (prostate cancer), HeLa (cervical cancer) and MCF-7 (breast cancer), cell lines evidenced from the in vitro antitumor studies performed by MTT assay (across 10-30 μM concentrations). The structural eminence of these synthesized molecules has emanated by designing the structural core by uniting the chromene, pyrimidine and phosphonate moieties into one, which has augmented their novelty and made them unreported. Further the deep structural activity relationship study investigations articulated that the title compounds are promising drug-like compounds and potential inhibitor of histidine amino acid residue present on the respective enzymatic proteins [3QJZ (A549), 3VHE (DU-145), 3V49 (PC-3), 3F81 (HeLa), & 3R7Q (MCF-7)] of the cell lines screened and are identified as responsible for the multi-faceted antitumor activities predicted in vitro. The obtained results were further supported by molecular docking studies, QSAR, ADMET, and bioactivity studies which have supported them as potential BBB penetrable molecules and proficient CNS active neuro-protective agents during drug delivery.

Multifunctional PLGA nanoparticles combining transferrin-targetability and pH-stimuli sensitivity enhanced doxorubicin intracellular delivery and in vitro antineoplastic activity in MDR tumor cells.

Abstract
Targeted delivery aims to enhance cellular uptake and improve therapeutic outcome with higher disease specificity. The expression of transferrin receptor (TfR) is upregulated on tumor cells, which make the protein Tf and its receptor vastly relevant when applied to targeting strategies. Here, we proposed Tf-decorated pH-sensitive PLGA nanoparticles containing the chemosensitizer poloxamer as a carrier for doxorubicin delivery to tumor cells (Tf-DOX-PLGA-NPs), aiming at alleviating multidrug resistance (MDR). We performed a range of in vitro studies to assess whether targeted NPs have the ability to improve DOX antitumor potential on resistant NCI/ADR-RES cells. All evaluations of the Tf-decorated NPs were performed comparatively to the nontargeted counterparts, aiming to evidence the real role of NP surface functionalization, along with the benefits of pH-sensitivity and poloxamer, in the improvement of antiproliferative activity and reversal of MDR. Tf-DOX-PLGA-NPs induced higher number of apoptotic events and ROS generation, along with cell cycle arrest. Moreover, they were efficiently internalized by NCI/ADR-RES cells, increasing DOX intracellular accumulation, which supports the greater cell killing ability of these targeted NPs with respect to MDR cells. Altogether, these findings supported the effectiveness of the Tf-surface modification of DOX-PLGA-NPs for an improved antiproliferative activity. Therefore, our pH-responsive Tf-inspired NPs are a promising smart drug delivery system to overcome MDR effect at some extent, enhancing the efficacy of DOX antitumor therapy.

Abstract
The purposes of this work are to evaluate the antimicrobial, antibiofilm, anticancer, and antioxidant abilities of anisotropic zinc oxide nanoparticles (ZnO NPs) synthesized by a cost-effective and eco-friendly sol-gel method. The synthesized ZnO NPs were entirely characterized by UV-Vis, XRD, FTIR, HRTEM, zeta potential, SEM mapping, BET surface analyzer, and EDX elemental analysis. Antimicrobial and antibiofilm activities of ZnO NPs were investigated against multidrug-resistant (MDR) bacteria and yeast causing serious diseases like urinary tract infection (UTI). The anticancer activity was performed against Ehrlich ascites carcinoma (EAC). Additionally, antioxidant scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) was observed. The synthesized ZnO NPs exhibited an absorption peak at 385.0 nm characteristic to the surface plasmon resonance (SPR). Data obtained from HRTEM, SEM, and XRD confirmed the anisotropic crystalline nature of the prepared ZnO NPs with an average particle size of 68.2 nm. The calculated surface area of the prepared ZnO NPs was 10.62 m2/g and the porosity was 13.16%, while pore volume was calculated to be 0.013 cm3/g and the average pore size was about 3.10 nm. The prepared ZnO NPs showed promising antimicrobial activity against all tested UTI-causing pathogens. It showed a prominent antimicrobial capability against Candida tropicalis with a zone of inhibition (ZOI) reaching 22.4 mm, 13 mm ZOI for Bacillus subtilis, and 12.5 mm ZOI for Pseudomonas aeruginosa. Additionally, the prepared ZnO NPs showed enhanced biofilm repression of about 79.33%, 72.94%, and 33.68% against B. subtilis, C. tropicalis, and P. aeruginosa, respectively. Moreover, the prepared ZnO NPs had a powerful antioxidant property with 33.0% scavenging ability after applied DPPH assay. Surprisingly, upon ZnO NPs treatment, cancer cell viability reduced from 100 to 58.5% after only 24 h due to their unique antitumor activity. Therefore, according to these outstanding properties, this study could give insights for solving serious industrial, pharmaceutical, and medical challenges, particularly in the EAC and UTI medications.

Abstract
In an attempt to enhance the previously observed antiproliferative capacity of 1-(p-toluenesulfonyl)cytosine (N-1-tosylcytosine, ligand 1), its copper(II) complex (Cu(1-TsC-N3)2Cl2, complex 2) was prepared and tested in vitro on various carcinoma and leukemia cells. The comparative in vitro studies using the ligand 1, the complex 2, CuCl2x2H2O salt (salt 3) and the 1:2 mixture of the salt 3 and ligand 1 (mixture 4) were performed on normal (WI38), human carcinoma (HeLa, CaCo2, MiaPaCa2, SW620), lymphoma (Raji) and leukemia (K562) cell lines. Significantly elevated concentration of the intracellular copper after treatment of K562 cells and HeLa cells during 2h with complex 2 (7.83 vs. 5.4 times) was detected by atomic absorption spectroscopy. Cytotoxicity was analyzed by MTT assay. We found that antiproliferative capacity of the tested compounds varies (IC50 after 72h of exposure: 0.6×10-6M to>100×10-6M). Leukemia and lymphoma cells were found the most sensitive to complex 2 which showed more than 100 times higher in vitro activity against K562 cells than ligand 1. Apoptotic morphological changes, an externalization of phosphatydilserine, and changes in the mitochondrial membrane potential of treated cells were found. The caspase-3 activity in HeLa and K562 cells was measured by caspase-3 colorimetric assay kit. Caspase-3 was not activated in the treated K562 cells while salt 3 and the mixture 4 in the HeLa cells significantly increased tested enzyme activity. These findings suggest that copper(II) in the molecular complex 2 by improving entry of the N-1-tosylcytosine 1 into cells increases its antiproliferative capacity. In summary, the present study demonstrated that complex 2 possesses an antileukemic effect on K562 cells, and its anticancer activity was attributed with induction of apoptosis. The exact mechanism of apoptosis induction by complex 2 must be further investigated.

Abstract
The encapsulation of antitumor drugs in nanosized systems with pH-sensitive behavior is a promising approach that may enhance the success of chemotherapy in many cancers. The nanocarrier dependence on pH might trigger an efficient delivery of the encapsulated drug both in the acidic extracellular environment of tumors and, especially, in the intracellular compartments through disruption of endosomal membrane. In this context, here we reported the preparation of chitosan-based nanoparticles encapsulating methotrexate as a model drug (MTX-CS-NPs), which comprises the incorporation of an amino acid-based amphiphile with pH-responsive properties (77KS) on the ionotropic complexation process. The presence of 77KS clearly gives a pH-sensitive behavior to NPs, which allowed accelerated release of MTX with decreasing pH as well as pH-dependent membrane-lytic activity. This latter performance demonstrates the potential of these NPs to facilitate cytosolic delivery of endocytosed materials. Outstandingly, the cytotoxicity of MTX-loaded CS-NPs was higher than free drug to MCF-7 tumor cells and, to a lesser extent, to HeLa cells. Based on the overall results, MTX-CS-NPs modified with the pH-sensitive surfactant 77KS could be potentially useful as a carrier system for intracellular drug delivery and, thus, a promising targeting anticancer chemotherapeutic agent.
