Abstract

Silica nanoparticles offer a promising platform for the delivery of drugs, in particular for the drugs which lack water solubility, target capability and have non-specific distribution, systematic toxicity and low therapeutic index. In this review, we focus on the synthesis and therapeutic (particularly, anti-cancer) applications of Curcumin loaded Silica Nanoparticles. Various surface modifications of silica nanoparticles have been discussed that are used to enhance their therapeutic applications. The characterization techniques and study of their biocompatibility have also been presented.

Abstract

The recent outbreak of Corona virus SARS-CoV-2 disease COVID-19 in the China and subsequent intermittent spread of infection to other countries has alarmed the medical and scientific community mainly because of lethal nature of this infection. Being a new virus in the category, the immediate emergency therapy is not available for the treatment of this disease, leading to widespread fear of infection and has created social issues for infected peoples. Herein, the epidemiology of COVID-19 infection, transmission characteristics of SARS-CoV-2 virus spread, effectiveness of preventive measures, coronavirus family, structural characteristics of virus, current literature advances for the diagnostics development (RT-PCR, CT-Scan, Elisa) and possible drug development based virus life cycle (Entry inhibitors, replication inhibitors, nucleoside, nucleotide, protease inhibitors, heterocyclic drugs, including biological therapeutics (monoclonal antibodies therapy, vaccine development) and herbal formulations have been reviewed. The chemical drug molecules with prospective application in the treatment of COVID-19 have been included in the discussion.

Abstract

A convenient and cost-effective methodology has been developed for the synthesis of some 2-substituted-4,6- diarylpyrimidines through one-pot conversion of various substituted chalcones, S-benzylthiouronium chloride (SBT) and morpholine using NiO nanoparticles as a reusable and economic catalyst. The deployment of this catalyst empowers the synthesis of variety of 2-(4- morpholinyl)-4,6-diarylpyrimidines in improved yields with easy work-up in a relatively short reaction time. The synthesized compounds have been studied for their potential anti-microbial and anti-tumor activities.

Keywords: cancer, proapoptotic genes, phytochemical, diet, HEK293, phytomedicine, anti-cancer nutrients, herbal drugs

Abstract

Severe side effects as well as the cost of chemotherapy necessitate the need for alternative therapies. Use of plant derived drugs is on the increase for the treatment of various diseases including cancer. This study was designed to explore the effects of the aqueous extract of the ripe fruits of Ziziphus jujube on MCF-7, HCT116 and HEK 293 cell lines to examine the possibility of it being developed as a therapeutic aid in cancer treatment. Cells were exposed to different doses (0-2mg/ml) of the aqueous extract for different time durations ranging from 24h to 72hr. Cell viability and the change in expression of various apoptosis related genes such as Bcl2, Bax, caspase-3 and caspase-9 were studied. Rate of proliferation of the cancer cells (MCF-7 and HCT116) decreased on exposure to the extract in a time and concentration dependent manner. Expression levels of all the genes studied, except Bcl2, showed an increase. Bcl2 expression was inversely proportional to time and concentration of the extract. Levels of activated caspases 3 and 9 were also increased. This report points to the possibility of developing the extract of Ziziphus jujube as a drug for the treatment of cancer.

Keywords: histopathology, oxidative stress, kidney, lipid peroxidation, toxicology

Abstract

The present study investigated the effect of monocrotophos, a commonly used organophosphate pesticide exposure in the kidney tissues of the swiss albino mice. Monocrotophos was administered at the sub-lethal doses of 1.25mg/kg, 2.5 mg/kg and 5.0 mg/kg body weight for 24 hr. Monocrotophos toxicity generated oxidative stress in the mice as evidenced by significant decrease in the activities of glutathione, superoxide dismutase and catalase enzymes. The exposure increased the lipid peroxidation and protein oxidation in a dose dependent manner. Oxidative stress generation also elicited cytotoxic effects on the mice kidney which were supported by the histopathological changes like degeneration in glomerulus, bowmen’s capsule and tubules, hemorrhage, mononuclear cell infiltration, tubular cast and congested blood vessels in a dose-dependent manner. In conclusion, the study indicated that monocrotophos exposure at various doses induces significant deleterious health effects in mice kidney tissues via oxidative stress generation.

Abstract

Selected novel β-lactam and thiazolidinone derivatives have been synthesized by the reaction of 4-methyl-1H-isochromen-1-one with 1,1-biphenyl-4,4-diamine, followed by the reaction with substituted benzaldehyde and further by the reaction with chloroacetyl chloride (for β-lactam type) and with thioglycolic acid (for thiazolidinone type) respectively . All the compounds were characterised by 1H NMR, IR and mass spectroscopy. These compounds were screened for in-vitro antimicrobial activity against Staphylococus aureus, E. coli, Pseudomonas aeruginosa strain. Some compounds have shown very good efficacy against antibacterial strain.

Abstract

Coumarin, triazoles and thiazolidinones are one of the most preferred and high valued scaffolds frequently used in medicinal chemistry. The synthesis of newly designed coumarin based triazolyl-thiazolidinones was performed and new compounds were obtained in good yields. The listed compounds were evaluated for their apoptotic activity and determined the minimal inhibitory concentrations for each of the compound on SCC-4 cells using MTT viability test. Furthermore, apoptotic inducer activity was assayed by detecting the expression of caspase-3, a key apoptotic enzyme.

Abstract

In this paper, we report the design, synthesis, in-silico, and in-vitro evaluations of a series of coumarin-phenylthiazole conjugates to inhibit cholinesterase enzymes. The coumarin and phenylthiazole derivatives have been synthesized separately, and further combined through covalent amine bond linkage. The synthesized compounds showed more inhibition towards BuChE than AChE, where 4-(3-bromophenyl)-1,3-thiazol-2-amine (7i) exhibited the strongest inhibition against BuChE with an IC50 value of 3.54 μM. For the conjugates, 3-{2-[4-(3-nitrophenyl)thiazol-2-ylamino]acetyl}chromen-2-one (8j) exhibited strongest inhibition with an IC50 value of 46.47 μM.  The better inhibition activities towards BuChE are also shown by 3-bromo and 2-fluoro derivatives. It was also observed that the substitution at 3-position, on phenylthiazole moiety produced better results against BuChE than 4-substituted counterparts.

Abstract

A series of Eu3+ doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+) was synthesized via sol-gel procedure at 950 oC. The optical characteristics of the materials were studied by Photoluminescence (PL) emission spectra. Upon 395 nm excitation and at 0.03 mole concentration of Eu3+ ion, these nanophosphors display optimum photoluminescence with most intense peak due to 5D07F2 (614-616) of dopant. Powder X-ray diffraction (PXRD) analysis proves that all synthesized materials are of crystalline nature and crystallinity improves on increasing temperature. Transmission electron microscopy (TEM) exhibited the spherical shape of particles in 13-30 nm size. Fourier Transformation infrared (FTIR) spectra showed peaks in 400-1000 cm-1 corresponding to gadolinium-oxygen and silicon-oxygen bond vibrations. In BaGd2Si3O10 material, Gd-O vibration is centered at 492 cm-1 and absorption band at 855 cm-1 is result of asymmetric vibrations of SiO in silicate tetrahedral unit. Due to excellent photoluminescence and suitable CIE coordinates, these materials could have brilliant applications in innovative displays.

Research Highlights

  • Series of trivalent europium doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+)fluorescent materials were synthesized successfully with sol-gel procedure.
  • The prepared samples were characterized using Photoluminescence analysis, X-ray diffraction study, Transmission Electron Microscopic analysis and Fourier Transform Infrared spectroscopy.
  • The CIE color coordinates values of phosphor confirmed the red color of complex approving the PL results.
  • X-ray diffraction pattern of these materials determined the particle size using Debye Scherrer’s equation.
  • Excellent photoluminescence response and nano size of these materials made them suitable for various innovative display applications.
