In silico virtual screening for new anti-cancer drug discovery is a cost-effective method as compared to traditional drug synthesis. From <em>Leguminosae</em>&nbsp;family 144 phytochemicals which were screened from the Dictionary of Natural Products (DNP) undergo molecular docking in comparison to approved drugs Gemcitabine, osimertinib, and Nintedanib against targeted proteins EGFR, BRAF, and KRAS. Only five phytochemicals are 2-Pyrrolecarboxylate, O-(3, 5-Dihydroxy-4-methoxy benzoyl), ?-Aldotripiperideine, O8-(2-Pyrrolecarbonyl), and Benzoyl&nbsp;with high docking scores were selected for further studies based on ADMET lab. In this article, phytochemicals that can inhibit protein growth causing lung cancer were screened and selected by using molecular docking or ADME analysis. In silico ADME studies of these selected phytochemicals suggest that 2-Pyrrolecarboxylate, O-(3,5-Dihydroxy-4-methoxy benzoyl), and O8-(2-Pyrrolecarbonyl) are completely safe, non-toxic, non-carcinogenic, non GERG blocker, do not cause liver injury and have high excretion rate and can be taken for further in vivo and in vitro studies to discover new chemotherapy against lung cancer.&nbsp;&nbsp;</p> 2023-12-31T00:00:00+00:00 Copyright (c) 2023 FRONTIERS IN CHEMICAL SCIENCES https://fcs.wum.edu.pk/index.php/ojs/article/view/77 Evaluation of Toxicity Effect of different Insecticides against Camponotus Compressus. 2024-01-01T17:25:40+00:00 Rimsha Waheed t@wum.edu.pk Naheed Bano t@wum.edu.pk Naeem Iqbal t@wum.edu.pk Sheikh Muhammad Azam sheikh.azam@ue.edu.pk Muhammad Asif Raza t@wum.edu.pk Warda khan t@wum.edu.pk Nargis Naheed t@wum.edu.pk Saima Samreen t@wum.edu.pk Nazuk Kareem t@wum.edu.pk Hasan Raza Javed t@wum.edu.pk Qasim Raza t@wum.edu.pk Muhammad Imran t@wum.edu.pk Muhammad Ejaz t@wum.edu.pk Muhammad Khalid t@wum.edu.pk <p>Carpenter ant species play a significant ecological role and are widely prevalent. Ants contribute to safeguarding plants from sap-sucking pest insects through natural biological control mechanisms. The current study was conducted to collect ants from Block B farms at Muhammad Nawaz Sharif University of Agriculture, Multan (MNSUAM), Pakistan. In current study, various insecticides (such as Imidacloprid, Fipronil, Methoxyfenozide, Emamectin benzoate, and Flubendiamide) were formulated at different concentrations (including 160, 80, 40, 20, 10, 5, and 0 ppm) for evaluation against carpenter ants. Notably, Fipronil and emamectin benzoate exhibited heightened toxicity, even at lower doses of 5 ppm and 10 ppm, resulting in the mortality of nearly all worker ants within 24 hours. In contrast, Imidacloprid displayed no distinct preference, as most worker ants remained alive even after 72 hours. These findings indicate that Fipronil and emamectin benzoate may serve as effective active ingredients for controlling carpenter ants. The data was meticulously recorded and subjected to rigorous statistical analysis using specialized software.</p> 2023-12-31T00:00:00+00:00 Copyright (c) 2023 FRONTIERS IN CHEMICAL SCIENCES https://fcs.wum.edu.pk/index.php/ojs/article/view/74 Biomedical Application of Gold Nanoparticles in Different Cancers 2023-12-06T09:48:55+00:00 Ayesha Siddiqua t@wum.edu.pk Noor Fatima noorifatima1452@gmail.com Rida Naz ridanaz5969@gmail.com Amna Bashir amnabashir817@gmail.com <p>Nanoparticles (NPs) have significantly advanced traditional cancer diagnosis, offering enhanced efficiency and expeditious processes. Their exceptional characteristics, including larger surface area, increased volume proportion, and superior targeting capabilities, contribute to their prominence. NPs exhibit low toxicity on healthy cells, thereby improving bioavailability and half-life. This is attributed to their effective penetration of epithelial fenestrations and tissues. Consequently, NPs have garnered considerable attention across diverse disciplines, emerging as highly promising materials in biomedical applications, particularly in the realm of disease diagnosis and treatment. In contemporary biomedical practices, numerous drugs are either presented in nanoparticle form or coated with them, facilitating precise targeting of tumors or afflicted organs while minimizing harm to normal tissues or cells. Various types of nanoparticles, encompassing metallic, magnetic, polymeric, metal oxide, quantum dots, graphene, fullerene, liposomes, carbon nanotubes, and dendrimers, exhibit significant potential in the domain of cancer treatment and diagnosis. Notably, nanoparticles have demonstrated intrinsic anticancer activity in several studies, exerting antioxidant effects and impeding tumor growth. Furthermore, they enable controlled drug release, enhancing efficiency and minimizing side effects. In the context of cancer diagnosis, nanomaterials like microbubbles serve as molecular imaging agents for ultrasound imaging. This comprehensive review delves into the diverse types of nanoparticles commonly employed in the diagnosis and treatment of cancer, elucidating their multifaceted applications and contributions to the field.</p> 2023-12-31T00:00:00+00:00 Copyright (c) 2023 FRONTIERS IN CHEMICAL SCIENCES https://fcs.wum.edu.pk/index.php/ojs/article/view/76 In vivo Assessment of Diltiazem HCl Immobilized Co-polymeric pH Sensitive Microgels 2023-12-16T06:42:00+00:00 Rabia Razzaq rrcapricon@yahoo.com Fahmida Jabeen fahmida-09-07@hotmail.com Zarmina Rashid t@wum.edu.pk Nazar Mohammad Ranjha t@wum.edu.pk <p>Novel stimuli responsive coplymeric (2-ethyl hexyl acrylate -co- itaconic acid diltiazem HCl loaded microgels were fabricated and characterized successfully to reduce the degradation of drugs in acidic pH of stomach resulting in reduced bioavailability to minimize dosing frequency and enhance patient compliance. To evaluate the clinical significance, <em>in-vivo</em> studies of recently prepared novel pH sensitive copolymeric microgels are performed and different pharmacokinetic parameters as maximum plasma concentration (C<sub>max</sub>), time to reach the maximum plasma concentration (T<sub>max</sub>), area under the plasma concentration-time curve (AUC <sub>0-?</sub>), half-life (t <sub>1/2?</sub>) and elimination rate constant (K<sub>21</sub>) are analyzed. The mean plasma concentration of sustained release DLZ loaded microgels showed higher T<sub>max</sub> for prepared microgels (4.0758±0.22 hrs) than standard drug solution. The half-life t<sub>1/2? </sub>of test microgels is relatively higher (5.68±5.86 hrs) whereas the C<sub>max </sub>is measured to be 41.06±2.02ng/ml for microgels with AUC<sub>0-?</sub> calculated as 460.35±39.99 ng.hr/ml. Elimination rate constant K<sub>21</sub> for DLZ microgels is 0.18 ± 0.07 hrs<sup>-1</sup> for which showed the absorption phase is extended and drug is present for a prolong period of time in the body. This study proved that novel prepared pH sensitive copolymeric p(EHA-co-IA) microgels released model drug in sustained release manner in&nbsp; pH sensitive medium.</p> 2023-12-31T00:00:00+00:00 Copyright (c) 2023 FRONTIERS IN CHEMICAL SCIENCES https://fcs.wum.edu.pk/index.php/ojs/article/view/75 Quantum Biochemistry: Unveiling the Quantum Coherence in Enzyme Catalysis 2024-01-05T15:19:06+00:00 Ameen Abbas rammayali01@gmail.com Mashhud-Ul-Hasan Abid t@wum.edu.pk Hafza Mahnoor t@wum.edu.pk Malaika Bukhari t@wum.edu.pk Rameen Malik t@wum.edu.pk Muhammad Jaon Haider t@wum.edu.pk Rabish Rafique t@wum.edu.pk Mishaal Fatima t@wum.edu.pk Taiba Shoaib t@wum.edu.pk <p><strong>Objective:</strong></p> <p>This study investigates the influence of quantum coherence in enzyme catalysis, aiming to elucidate its role in biochemical processes.
