Human phosphatidyl inositol mannoside kinases (Pim kinases) are important biological target for discovery of new anticancer agents. In addition, Pyrimidines have a good contribution as building blocks of many anticancer agents. Hence, a literature survey about Pim kinases inhibitors and pyrimidine-based anticancer agents have been achieved. In this survey, we introduced Pim kinase inhibitors under clinical assessment including imidazo[1,2-b ]pyridazines, isatins, thiazolidine-2,4-diones, pyridinamines, and diaminopyrazoles. In addition, Pim kinase inhibitors under development were presented. These compounds include pyridine-quinolines, benzimidazoles indoles, cyano pyridines, pyridothieno[3,2-d ]pyrimidin-4-ones, oxadiazole, and 3,4-dihydropyrrolo[1,2-a]pyrazin-1(2 H )-ones. Furthermore, different pyrimidine-based anticancer agents have been discussed.

Depending to the WHO, antibiotic resistance and limited anticancer and antimicrobial therapies continue to be serious worldwide health challenges. Current medicines' efficacy suffers by issues such as insufficient solubility, stability, and side effects. To create effective and dependable therapies against antibiotic resistance and robust illnesses, new techniques and strategies are required. Several metal nanoparticles synthesised via green synthesis or chemical synthesise, such as gold (Au), zine (ZnO), and others, have shown promising biological effects against malignancies and a wide spectrum of microbial illnesses caused by multi-drug resistant bacteria. An eco-friendly biosynthetic technique was used to create zinc oxide nanoparticles (ZnO NPs), as well as their antibacterial and anticarcinogenic activities. Extracellular synthesis of nanoparticles made of zinc oxide ZnO nanoparticles was achieved in the current work using the cell filtrate of the endophytic fungus Fusarium chlamydosporum MW341592.1 isolated from healthy leaves of Eucalyptus sideroxylon plant. The nanoparticles were characterised by UV-VIS spectroscopy, X-ray diffraction (XRD), dynamic light scattering (DLS), transition electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX). The UV-Vis absorption spectra of the produced ZnO NPs showed bands in the UV area at (305) nm. Transmission electron microscopy TEM revealed average sizes of 19.3 nm, while shape revealed spherical like shape. The distinctive pattern of crystalline ZnO NPs was revealed by XRD diffract grams. Furthermore, Biological assay has shown that raising the nanoparticle concentration lowers the number of HCT-116 human colon cancer cells and CACO2 human intestinal cancer cells, as well as antibacterial pathogens Escherichia coli and Pseudomonas aeruginosa.

Development and validation of three simple, eco-friendly, accurate and precise chemometric models have been presented for the spectrophotometric determination of ciprofloxacin (CIP), indomethacin (IND), and metronidazole (MET) residues in production wastewater samples. These methods are classical least square (CLS), principal component regression (PCR) and partial least square (PLS-1). A 3-factor 5-level experimental design was built leading to 25 mixtures containing different ratios of CIP, MET, and IND. Thirteen mixtures were used as a training set, and the other twelve were used as a validation set. Using of multi-wavelengths instead of the single wavelength spectrophotometry has greatly improved the precision and predictive abilities of these multivariate calibrations. The proposed methods have been found to be accurate, precise and can be used for determination of the drugs in pure form and industrial wastewater samples without preliminary separation steps. The methods described were used to accurately assess the drug residues in laboratory-prepared mixtures and actual industrial wastewater samples to confirm that it is free from these drug residues so it can be recycled and used for irrigation and other purposes.

Cancer is a disease in which human cells grow uncontrollably and spread to other body parts. Cancer is the second leading cause of death globally and accounted for 9.6 million deaths in 2022 according to the statistics of the World Health Organization. Cancer can begin in any part of the human organs when the normal cell loses the ability to control the division cycle, which may inhibit apoptosis. Cancer cells grow and multiply by activating the angiogenetic factors to build new capillaries that can supply tumor tissue with nutrients. Cancerous tumors spread into or invade nearby tissues and can travel to other organs in the body to form new carcinogenic tissue by metastasis. The goal of treatment is control growth of cancer cells, and induction the programmed cell death. Pyrimidines and its derivatives have been found as effective and valuable pharmacophoric units in medicinal chemistry to design and develop a wide range of bioactive compounds. The present review summarizes the advances in lead compounds of pyrimidines hybrids and their related heterocycles in the treatment of cancer. Moreover, the review also helps to intensify the drug development process by providing an understanding of the potential role of these hybridized pharmacophoric features as VEGFR-2 inhibitors.

Voriconazole is a triazole antifungal with a half-life of 1.7 hours and 96% oral bioavailability. The oral route is the most popular of drug delivery routes. However, there are a few limitations to the traditional dosage form, for instance, fluctuations in plasma drug level. Sustained drug delivery system overcomes these limitations; it helps to maintain stable plasma drug concentrations by decreasing drug r elease and extending the duration of the effect. The main purpose of this study was to formulate voriconazole sustained release dosage form to enhance efficacy, decrease dose frequency, decrease its side effects, and improve patient compliance. The study explored various formulations for producing the sustained-release (S.R) dosage form, as well as assessed the drug's release kinetics and its stability. Methodology : Fourier-transform Infrared Spectroscopy was used to investigate drug-polymer compatibility. The micromeritics of voriconazole powder and its blends were evaluated. Different sustained release tablets were formulated utilizing a wet granulation process and acrylic polymers (Eudragit) i.e., Eudragit RL100 and RS100 alone and as mixtures with different ratios, in different concentrations. In-vitro drug release of formulae was performed for 24 hours. The formula with desired control of drug release and complied with dissolution specifications for SR dosage forms was further evaluated for its stability by storage for 3 months at 30 o C and 40 o C and 75% relative humidity. Results : no interaction was observed between voriconazole and polymers using FTIR. The powder blends micromeritics were found to be in accordance with the specification. Tablets showed release from 37.29 to 76 % up to 24 hr using USP type I technique. It was found that as polymer concentration increased, the drug release from tablet decreased. The selected formulation F13 which containing 5% of Eudragit RL100:RS100 at a ratio of (10:1) was found to be stable. Conclusion : The obtained data concluded that the F13 formula gave more prominent S.R effect than using Eudragit RL100 or RS 100 alone.
{"title":"PREPARATION AND EVALUATION OF SUSTAINED RELEASE MATRIX FORMULATIONS OF VORICONAZOLE","authors":"Shereen Abd El Gawad, M. Marzouk, A. Ammar","doi":"10.21608/ajps.2023.311244","DOIUrl":"https://doi.org/10.21608/ajps.2023.311244","url":null,"abstract":"Voriconazole is a triazole antifungal with a half-life of 1.7 hours and 96% oral bioavailability. The oral route is the most popular of drug delivery routes. However, there are a few limitations to the traditional dosage form, for instance, fluctuations in plasma drug level. Sustained drug delivery system overcomes these limitations; it helps to maintain stable plasma drug concentrations by decreasing drug r elease and extending the duration of the effect. The main purpose of this study was to formulate voriconazole sustained release dosage form to enhance efficacy, decrease dose frequency, decrease its side effects, and improve patient compliance. The study explored various formulations for producing the sustained-release (S.R) dosage form, as well as assessed the drug's release kinetics and its stability. Methodology : Fourier-transform Infrared Spectroscopy was used to investigate drug-polymer compatibility. The micromeritics of voriconazole powder and its blends were evaluated. Different sustained release tablets were formulated utilizing a wet granulation process and acrylic polymers (Eudragit) i.e., Eudragit RL100 and RS100 alone and as mixtures with different ratios, in different concentrations. In-vitro drug release of formulae was performed for 24 hours. The formula with desired control of drug release and complied with dissolution specifications for SR dosage forms was further evaluated for its stability by storage for 3 months at 30 o C and 40 o C and 75% relative humidity. Results : no interaction was observed between voriconazole and polymers using FTIR. The powder blends micromeritics were found to be in accordance with the specification.
