The highly nuanced transition from an inflammatory process to tumorigenesis is of great scientific interest. While it is well known that environmental stimuli can cause inflammation, less is known about the oncogenic modifications that chronic inflammation in the tissue microenvironment can bring about, as well as how these modifications can set off pro-tumorigenic processes. It is clear that no matter where the environmental factors come from, maintaining an inflammatory microenvironment encourages carcinogenesis. In addition to encouraging angiogenesis and metastatic processes, sustaining the survival and proliferation of malignant transformed cells, and possibly altering the efficacy of therapeutic agents, inflammation can negatively regulate the antitumoral adaptive and innate immune responses. Because chronic inflammation has multiple pathways involved in tumorigenesis and metastasis, it has gained recognition as a marker of cancer and a desirable target for cancer therapy. Recent advances in our knowledge of the molecular mechanisms that drive cancer's progression demonstrate that inflammation promotes tumorigenesis and metastasis while suppressing anti-tumor immunity. In many solid tumor types, including breast, lung, and liver cancer, inflammation stimulates the activation of oncogenes and impairs the body's defenses against the tumor. Additionally, it alters the microenvironment of the tumor. As a tactical approach to cancer treatment, these findings have underscored the importance of targeting inflammatory pathways. This review highlights the role of inflammation in cancer development and metastasis, focusing on its impact on tumor progression, immune suppression, and therapy resistance. It examines current anti-inflammatory strategies, including NSAIDs, cytokine modulators, and STAT3 inhibitors, while addressing their potential and limitations. The review emphasizes the need for further research to unravel the complex mechanisms linking inflammation to cancer progression and identify molecular targets for specific cancer subtypes.

: Mitosis of somatic cells produces a daughter cell. Apoptosis, a naturally programmed cellular death mechanism, kills abnormal cells produced by mitosis. Cancer can develop when this equilibrium is disrupted, either by an upsurge in cell propagation or a reduction in tissue demise. Cancer therapy aims to cause cancer cells to die while inflicting little harm to healthy cells. This review of apoptotic mechanism processes improves our understanding of how certain malignancies begin and develop. The current cancer treatments can operate either by inducing apoptosis or causing direct cell damage. An insight into the resistance to apoptosis may explicate why malignancy treatments fail in some situations. New therapies grounded on our understanding of apoptotic processes are being developed to induce apoptosis of cancer cells while limiting the simultaneous death of normal cells. Various biological activities require redox equilibrium to function properly. : Antineoplastic medications that cause oxidative stress by raising ROS and blocking antioxidant mechanisms have recently attracted much interest. The rapid accumulation of ROS impairs redox balance and damages cancer cells severely. Here, we discuss ROS-instigating malignancy therapy and the antineoplastic mechanism used by prooxidative drugs.

: Cancer is considered one of the gruelling challenges and poses a grave health hazard across the globe. According to the International Agency for Research on Cancer (IARC), new cancer cases increased to 18.1 million in 2018, with 9.6 million deaths, bringing the global cancer rate to 23.6 million by 2030. In 1942, the discovery of nitrogen mustard as an alkylating agent was a tremendous breakthrough in cancer chemotherapy. It acts by binding to the DNA, and creating cross linkages between the two strands, leading to halt of DNA replication and eventual cell death. Nitrogen lone pairs of ‘nitrogen mustard’ produce an intermediate 'aziridinium ion' at the molecular level, which is very reactive towards DNA of tumour cells, resulting in multiple side effects with therapeutic consequences. Owing to its high reactivity and peripheral cytotoxicity, several improvements have been made with structural modifications for the past 75 years to enhance its efficacy and improve the direct transport of drugs to the tumour cells. Alkylating agents were among the first non-hormonal substances proven to be active against malignant cells and also the most valuable cytotoxic therapies available for the treatment of leukaemia and lymphoma patients. This review focus on the versatile use of alkylating agents and the Structure Activity Relationship (SAR) of each class of these compounds. This could provide an understanding for design and synthesis of new alkylating agents having enhanced target specificity and adequate bioavailability.

N-Methyl-d-aspartate receptor (NMDAR)-mediated excitotoxicity has been implicated in multi-neurodegenerative diseases. Owing to dearth of efficacy and adverse effects of NMDA receptor antagonists, search for herbal remedies acting like salutary agents is a dynamic expanse of investigation to contest neurodegenerative disease. Withania somnifera (W. somnifera) has been used since antiquity as a nerve tonic and nootropic agents in Ayurveda, an old Indian system of medicine. In the present study, we have explored phytochemicals from Ayurvedic herb W. somnifera as an inhibitor of NMDA receptor-mediated excitotoxicity through allosteric reticence of the GluN1-GluN2B encompassing NMDARs by dint of molecular docking and dynamics studies. Thus, steering and constraining GluN1-GluN2B may be effective in the management of neurodegenerative diseases including Alzheimer’s disease. Out of the curtained phytochemicals, chlorogenic acid revealed significant docking scores of –8.856 and –8.645 kcal/mol and free binding energies of –49.84 and –50.67 kcal/mol in Chain AB and Chain CD of NMDARs, respectively. Chlorogenic acid in AB chain forms four hydrogen bonding with Glu110, Arg115, Leu135 and Asp136 amino acid residues and five hydrogen bond with Glu106, Ala107, Ile133, Ile335and Arg155 amino acid residues of CD chain. To further validate the interaction of top scored molecule chlorogenic acid, molecular dynamics study of 100 ns was carried out. It indicated that the protein–ligand complex was stable throughout the simulation period, and minimal backbone fluctuations have ensued in the system. In silico pharmacokinetic predictions of the screened phytochemicals were within the defined range described for human use. Communicated by Ramaswamy H. Sarma

Background: Pyrazole is a component of a diversity of bioactive heterocyclic congeners with a broad-spectrum range of biological and pharmacological uses. Designing novel pyrazole and its analogues, revealing new routes for synthesizing this nucleus, exploring various potencies of that heterocycles, and looking for possible applications of pyrazoles are all becoming more important due to their numerous potential applications.
