Special Issue Information

Dear Colleagues,

Recent experimental developments in nanoformula of different biomedical activity of  natural plant extracts and efficacy of active compounds are among the most highly-exploited research systems in the field of cancer biology. Driven by the current state of knowledge of biomedical efficiency of the drugs and some natural agents, the need to maintain structural material integrity and reliability assets under harsh environments, and a renewed impetus towards durability of new nanostructured against several diseases like cancer and metabolic diseases like Diabetes , have seen a huge demand on experimental, theoretical and modelling activities.

Studying the hepatoprotective , neuroprotective , testicular protective activities of the natural extracts and a lot of active compounds against different disorders and aging progression and make high benefits of these compounds by complete chemical characterization and spectroscopic analysis. Beside testing the wound healing assay of some compounds and testing the activities of antibiotic metal drug complexes and flavonoid metal drug complexes against environmental infections.

This scope of this Special Issue will serve as a forum for papers in the following concepts:

  • Experimental research, knowledge and new ideas about protective effects of natural extracts against different diseases including cancer and diabetes.
  • Recent developments in activities of natural products and active compounds in treatment of diseases.
  • Anti-cancer activities of some natural plant extracts and Nano-formula.
  • Experimental and processing high-performance cromatography with exposure to high temperatures, high stress, and other extreme environmental applications.
  • The latest development of anticancer and anti-diabetic agents from natural extracts and different chemical agents.
  • Computer modeling, simulation to predict nanoparticles' properties, performance  in service environments.
  • Metal drug and natural extract complexes  with antibiotics and  falvonoids' agents with chemical characterization and spectroscopic analysis against infections.

Abstract
Magnesium(II), calcium(II), chromium(III), zinc(II), copper(II), and selenium(IV) sitagliptin (STG) complexes—with the general formulas [Mg(STG)2(Cl)2]·6H2O, [Ca(STG)2(Cl)2], [Cr(STG)2(Cl)2]Cl.6H2O, [Zn(STG)2(Cl)2], [Cu(STG)2(Cl)2]·2H2 [...] Read more.
Magnesium(II), calcium(II), chromium(III), zinc(II), copper(II), and selenium(IV) sitagliptin (STG) complexes—with the general formulas [Mg(STG)2(Cl)2]·6H2O, [Ca(STG)2(Cl)2], [Cr(STG)2(Cl)2]Cl.6H2O, [Zn(STG)2(Cl)2], [Cu(STG)2(Cl)2]·2H2O, and [Se(STG)2(Cl)2]Cl2, respectively—were designed and synthesized by the chemical reactions between metal(II, III, and IV) chloride salts with an STG ligand in situ methanol solvent in a 1:2 stoichiometric ratio (metal:ligand). Tentative structures of the complexes were proposed based on elemental analysis, molar conductance, magnetic moments, thermogravimetric analysis, and spectral (infrared, electronic, and 1H NMR) data. The particle size and morphological investigation were checked on the bases of scanning electron microscopy, transmission electron microscopy, and X-ray powder diffraction analyses. All the Mg2+, Ca2+, Cr3+, Zn2+, Cu2+, and Se4+ complexes were found to be six-coordinated, wherein the STG ligands act as bidentate chelating agents. This study demonstrates that pancreatic tissues are affected by the induction of experimental diabetes mellitus and clarifies the potential of the synthesized STG complexes, which was found to more significantly improve insulin secretion and the pancreatic and glycometabolic complications of diabetic rats than STG alone.
