    Abstract The PD-1/PD-L1 pathway plays a significant role in inhibiting, escaping from immune response, and promoting self-tolerance of the tumour. Dostarlimab is a selective humanized monoclonal antibody designed to target PD-1 and block its activity with PD-L1, which further prevents the escape of tumour cells from immune surveillance. It got accelerated approval from the FDA for treating adults with mismatch repair deficient, recurrent, or advanced endometrial cancer, and studies confirmed its beneficial effects. A recently published clinical trial reported 100% remission of advanced rectal cancer without significant side effects in the participants. This clinical trial is still going on and enrolling patients with different types of cancer, including ovarian cancer, melanoma, head and neck cancer, and breast cancer therapy. The clinical trial result gave hope and proof to the medical fraternity and patients for better treatment. The focus of this review is to summarise pre-clinical and clinical studies of Dostarlimab.

    Abstract Tridax procumbens is a flowering plant of the Asteraceae family with a wide range of medicinal uses like anti-inflammatory, anti-diabetic, anti-microbial, immunomodulatory, etc. This study aimed to investigate the anti-cancerous activity of human lung cancer for targeting luteolin, a phytochemical of Tridax procumbens. The computational study has been done for studying the structural properties of luteolin. The drug-likeness of the molecule has been predicted by virtual screening of ADMET properties. The molecular docking technique of the in-silico method is performed to check the complex formation between protein and ligand. The reactivity and stability of the molecule are investigated with the help of molecular dynamics (MD) simulations. In the present work, we have tried to establish a strong candidature of any of the phytochemical of Tridax Procumbens as an inhibitor against human lung cancer.

    Abstract The proteasome subunit β5 (PSMβ5) is a chief target of proteasome inhibitors (PIs) for treatment of multiple myeloma (MM). The relevance of PSMβ5 mutations and their functional impact on the development of resistance to PIs have been demonstrated recently. Therefore, this present study deals with an in-depth E-pharmacophore based screening and repurposing of FDA-approved drugs that could target PSMβ5 for MM. Our molecular docking-based investigation revealed risedronate and zoledronate as potential alternative therapeutic molecules for targeting the PSMβ5 gene. Risedronate and zoledronate displayed high binding affinity (-9.51 and -8.56 kcal/mol respectively) to PSMβ5. Moreover, 100 ns molecular dynamics simulation analysis of docking complexes revealed risedronate and zoledronate with a superior binding free energies and stable interactions with PSMβ5. The RMSD plot shows that the risedronate-PSMβ5 (mean: 0.24 nm) and zoledronate-PSMβ5 (mean: 0.25 nm) complexes are identical and stays stable until 100 ns. We further validated the activity of zoledronate in MM cell lines RPMI8226 and U266 where zoledronate showed significant anti-proliferative and apoptotic activity. Importantly, zoledronate showed an enhanced anti-proliferative activity when combined with bortezomib in MM cell lines. Thus, this study demonstrates that combining bortezomib with zoledronate could have a significant impact on reducing MM cell growth and can be an alternative strategy for treating MM.

    Abstract The emergence of the coronavirus disease-2019 pandemic has led to an outbreak in the world. The SARS-CoV-2 is seventh and latest in coronavirus family with unique exonucleases for repairing any mismatches in newly transcribed genetic material. Therefore, drugs with novel additional mechanisms are required to simultaneously target and eliminate the virus. Thus, a newly deciphered N protein is taken as a target that belongs to SARS-CoV-2. They play a vital role in RNA transcription, viral replication and new virion formation. This study used virtual screening, molecular modeling and docking of the 8987 ligands from Asinex and PubChem databases against this novel target protein. Three hotspot sites having DScore ≥1 (Site 1, Site 2 and Site 3) for ligand binding were selected. Subsequently, high throughput screening, standard precision and extra precision docking process and molecular dynamics concluded three best drugs from two libraries. Two antiviral moieties from Asinex databases (5817 and 6799) have docking scores of -10.29 and -10.156; along with their respective free binding energies (Δ

    Abstract This study explains the vibration and interaction of three pharmaceutically active hydrazine derivatives, (E)-3-((2-(2,5-difluorophenyl)hydrazono)methyl)-4H-chromen-4-one (DFH), (E)-3-((2-(4-(trifluoromethyl)phenyl)hydrazono)methyl)-4H-chromen-4-one (TMH), and (E)-3-((2-(3,5-bis(trifluoromethyl)phenyl)hydrazono)methyl)-4H-chromen-4-one (BPH) using theoretical approach. The trend in chemical reactivity and stability of the studied compounds was observed to show increasing stability and decreasing reactivity and this was obtained from orbital energies. The effect of bromine and chlorine atoms, instead of fluorine atoms, is also noted. Surface analysis on the covalent bond was attained by ELF and LOL analysis. Biological activities were predicted using molecular docking studies. Docking results were analyzed with standard drugs, 5-fluorouracil/piperine. Antitumor activity of hydrazine derivatives was found to be higher than reference ones. Molecular dynamics (MD) simulation was performed for 100 ns to validate the stability behavior of hydrazine derivatives with the dual specificity threonine tyrosine kinase (TTK) protein. RMSD, RMSF, Rg, SASA, and intermolecular analysis of DFH, TMH, and BPH with threonine tyrosine kinase forms stable ligand-protein interactions. The molecular and predictive biological properties of three pharmaceutically active hydrazine derivatives which can be helpful to researchers in future experimental validation through in vitro and in vivo studies.

    Abstract Objective: The objective of this study was to assess the pharmacy professionals' understanding and viewpoints on drug information center (DIC) services and differences, if any, with pharmacologist's survey conducted earlier. Materials and Methods: An electronic cross-sectional knowledge, practice, and attitude survey was carried out. A questionnaire in the form of the hyperlink was sent to pharmacy professionals through e-mail, Facebook messenger, and WhatsApp. Factors linked to pharmacy professionals' vision in expanding countrywide DIC services were studied with logistic regression in R. Results: A total of 125 pharmacy professionals responded. The participant believing in the published literature as a standard reference for establishing and running the DIC services; participants identifying more challenges in the day-to-day DIC functioning; and participants believing in the ability of DIC in reducing morbidity, mortality, and cost of care had 4.76 (95% confidence interval [CI] = 0.97–6.44), 4.24 (95% CI = 0.97–6.44), and 2.43 (95% CI = 0.97–6.44) times association with good knowledge score. Good attitude scores were discovered of participants working in fully and partially functional DIC (odds ratio [OR] = 9.66, CI = 0.97–6.44 and OR = 9.49, CI = 0.97–6.44) to participants not involved in DIC duties. The participant who understood DIC services' real purpose had 2.83 (95% CI = 0.97–6.44) times association with good practice scores. Overall, pharmacy professionals carried better attitude scores, but lesser knowledge, and practice scores than pharmacology professionals. Conclusion: Lower knowledge and practice score of pharmacy professionals asks for training in critical appraisal of published literature and due modifications in graduate and postgraduate curricula. A collaborative approach between pharmacists and pharmacologists is needed to improve the quality of drug information services and evidence-based medicine practice in low-resource countries like India.

    Abstract Theoretical analyses of two phenothiazine derivatives, 10-[3-(dimethylamino)-2-methylpropyl]phenothiazine-2-carbonitrile (CYM) and 2-[4-[3-(2-chlorophenothiazin-10-yl)propyl]piperazin-1-yl]ethanol (PAZ) are reported using density functional theory (DFT) and molecular dynamics (MD) simulations. Spectroscopic studies, different electronic and chemical parameters are predicted. Red and yellow in electrostatic potential plot is in rings and oxygen atom in PAZ and C≡N and rings in CYM are sensitive to nucleophilic attacks. The blue in hydrogen atoms refer to electrophilic attack in both PAZ and CYM. Stability of the protein-ligand complex formed with these derivatives and angiotensin-converting enzyme 2 (ACE2) was investigated using MD simulation. Radius of gyration of C-alpha atom of 6VW1 displayed the conformational convergence toward a compact structure leading to stable 6VW1-ligand complex which are also in agreement with root mean square fluctuation (RMSF) values.

    Abstract Drug delivery devices are an effective way to minimize anticancer drug toxicity and nanostructures are used in the targeted drug delivery. In the present work, adsorption and interaction behavior of 4-(dimethylaminodiazenyl)-1H-imidazole-5-carboxamide (DAIC) with nano complexes (graphene, fullerene and fullerene like metal cages) are reported theoretically. From the reactivity studies, the electrophilicity index of DAIC-nanoclusters are increasing and this gives the bioactivity of the nanocluster systems. Adsorption energy is highest in the case of AlP and lowest in the case of BP clusters. Mulliken charge distribution of all systems is an evidence for chemical enhancement. DAIC adsorption over nanocages causes changes in electronic properties resulting in chemical enhancement and variation in Raman spectra which suggests that nanocages could be a good candidate for DAIC detection.
