Synthesis and in vitro Evaluation of Polymeric Prodrug of Ibuprofen with Amino Acid Spacer
The present work is an agreement with simple and efficient method of improving the therapeutic efficacy of ibuprofen by masking its acidic moiety. It aims to reduce gastrointestinal side effects by controlling the rate, duration and site of release. This is achieved by synthesis and evaluation of po
Determination of Carprofen in the Presence of some Hydrosoluble Vitamins of Group B by HPLC Method
A new HPLC method have been developed and validated for simultaneous determination of carprofen, vitamin B1, B6 and B12 in veterinary pharmaceutical preparations medicines. The method used a Hypersil GOLD aQ (250 x 4.6 mm, 5 µm) column, under the following chromatographic conditions: gradient e
Synthesis and characterization of a new retinoic acid ECPIRM as potential chemotherapeutic agent for human cutaneous squamous carcinoma
Cutaneous squamous cell carcinoma (CSCC) is one of the most common cancers worldwide, requiring effective therapeutic interventions. Retinoids are important chemopreventive and therapeutic agents for a variety of human cancers including CSCC. In this study we synthesized a novel retinoic derivative
Synthesis of Isoxazole Moiety Containing Thieno[2,3-d]pyrimidine Derivatives and Preliminarily in vitro Anticancer Activity (Part II)
21 new structures of isoxazole-moiety-containing thieno[2,3-d]pyrimidine derivatives(3a~3u) were synthesized for the first time and characterized using IR, 1H NMR, 13C NMR, ESI-MS and elemental analysis techniques. And then their in vitro anticancer activity against lung cancer A549, colorectal HCT1
Design, Synthesis, and Evaluation of Genistein Analogues as Anti-Cancer Agents
Genistein is a bioactive isoflavone derived from soybeans. The tie-in between the intake of genistein and the decreased incidence of some solid tumors (including prostate cancer) has been demonstrated by epidemiological studies. The potential of genistein in treating prostate cancer has also been di
Structure-based Discovery of Novel Antibacterials
An increasing fraction of bacterial isolates show reduced susceptibility to our most trusted antibiotics. In order to prevent this serious medical problem, the elaboration of new types of antibacterial agents or the expansion of bioactivity of the previous drugs is a very important task. Different t
A Simple and Sensitive Hydrazine Electrochemical Sensor Based on Platinum Nanoclusters
In this paper, platinum nanoclusters (PtNCs) were synthesized by less sophisticated equipments with low cost and tedious procedures, and then applied to construct a simple electrochemical hydrazine sensor rapidly within the applied potential. PtNCs were proved to have advantages over platinum nanopa
Ozone Dosage Effect on C6 Cell Growth: in Vitro and in Vivo Tests
C6 rat glioma cells are one of the most aggressive carcinogenic tumors, due to its high mortality rate in human beings and animals. The current treatment for this illness includes surgery, radio and chemotherapy, showing relapse in patients treated with those therapies. Since the ozone was found to
Investigation of 2-Fluoro Benzoic Acid Derivatives as Influenza A Viral Sialidase Selective Inhibitors
Neuraminidase (NA), a glycoside hydrolase enzyme, plays pivotal roles in controlling biological functions not only of influenza viruses but also of humans. Zanamivir and oseltamivir designed to target influenza neuraminidase have become extensively used for influenza clinical treatment as its high a
Intracellular ROS Generation Mediates Maleimide-induced Cytotoxicity in Leukemia Cells
Maleimides consist of an important class of compounds easily synthesized with multiple functional group modification that provides expressive pharmacological properties including, antitumoral activity, mediated mainly by oxidative stress. For this reason, the present study was designed to evaluate t
Quercetin Increase the Chemosensitivity of Breast Cancer Cells to Doxorubicin Via PTEN/Akt Pathway
Our previous study indicated that nontoxic doses of quercetin (Que) could increase the chemosensitivity of breast cancer cells to doxorubicin (Dox) although the mechanism still remains elusive. Therefore, in this study, we aimed to investigate the underlying mechanisms. MCF-7 cells and MCF-7/dox cel
Recent Innovations of Molecularly Imprinted Electrochemical Sensors Based on Electropolymerization Technique
Electrochemical sensors based on molecularly imprinted polymer (MIP) have attracted great attention over the past ten years. Among the strategies for the preparation of MIP modified electrode, electropolymerization is a potential technique, which can deposit a MIP film with special selectivity on th
A Novel Multi-functional Fluorescent Probe for Cu2+, Fe3+ and Ag+ Based on a Pyrimidine Thiourea Derivative
A multi-functional “turn-off” fluorescent probe, N-[[(6-Amino-1,2,3,4-tetrahydro-1,3- dimethyl-2,4-dioxo-5-pyrimidinyl)amino]thioxomethyl]- benzamide, was synthesized and characterized. The probe showed high sensitivity and selectivity towards copper(II), iron(III) and silver(I) ions via quenchi
