New 2-indolinone-indole hybrid compounds carrying a benzoyl moiety as tyrosine kinase inhibitors.

In this study, new 2-indolinone-indole hybrid compounds (4a-s) carrying a benzoyl moiety were synthesized and their cytotoxic effects were examined against pancreatic (MIA-PaCa-2) and colon (HT-29 and HCT-116) cancer cells by MTT assays. Most of the tested compounds exhibited a better inhibitory activity and safety profile than the reference standard sunitinib malate against MIA-PaCa-2 and HCT-116 cancer cells. Compound 4e displayed the greatest cytotoxic effect on HCT-116 cell with an IC value of 0.

Fabrication and characterization of silver nanowire-coated porous alginate wet-laid webs for wound dressing applications.

Wound care presents an imposed financial burden for healthcare organizations, prompting the need for novel and cost-efficient dressings. In this study, we address this challenge by introducing a novel approach to fabricate antibacterial alginate-based fibrous materials using a combination of wet spinning and the wet-laying method, which offer advantages including structural and functional properties such as breathability, nontoxicity, biocompatibility, and cost-effectiveness. The wet spinning method was employed to develop porous and non-porous Ca-alginate fibers with diameters of 100 ± 4.

Vitamin D increases the efficacy of cisplatin on bladder cancer cell lines.

Background: 1,25(OH)2D3(Calcitriol), which is a broad regulatory molecule, plays a role in changing the efficacy of chemotherapeutic drugs. Cisplatin is one of a current standard chemotherapy regimen for bladder cancer. Increasing the effectiveness of the treatment and reducing the side effects to chemotherapeutics are of great importance in bladder cancer.

Poly(L-lactic acid)/poly(ethylene oxide) based composite electrospun fibers loaded with magnesium-aluminum layered double hydroxide nanoparticles.

Two types of MgAl layered double hydroxide nanoparticles, MgAl LDH, at Mg:Al ratio of 2:1 and 3:1were prepared and used as inorganic fillers to improve the mechanical properties of poly(lactic acid)/poly(ethylene oxide) (PLA/PEO) electrospun composite fibers. Their detailed structural characterization was performed using X-ray diffraction (XRD) and transmission electron spectroscopy (TEM) techniques. Spectroscopic, thermal, mechanical, and morphological properties of the electrospun composite fibers, and cell proliferation on their surface, were examined.

The evaluation of anticancer activity by synthesizing 5FU loaded albumin nanoparticles by exposure to UV light.

In this study, as a new synthesis method, UV light was employed as a type of cross-linking agent to control drug storage and to produce nanoparticles of different sizes and to stabilize the nanoparticles for the first time. We showed that the exposure time of the 5FU albumin solution to UV light produces differences in the size and characterization of the nanoparticles and also produces different cytotoxic effects on MCF-7 breast cancer cells. While the 5FU-A1 nanoparticles we synthesized with 1 h UV storage were approximately 43 nm, the 5FU-A2 nanoparticles we synthesized with UV storage for 3 h increased to an average of 300 nm.
