Design, Synthesis, And Antiproliferative Activity Of Benzopyran-4-One-Isoxazole Hybrid Compounds, Shilpi Gupta, Shang Eun Park, Saghar Mozaffari, Bishoy El-Aarag, Keykavous Parang, Rakesh Kumar Tiwari

Pharmacy Faculty Articles and Research

The biological significance of benzopyran-4-ones as cytotoxic agents against multi-drug resistant cancer cell lines and isoxazoles as anti-inflammatory agents in cellular assays prompted us to design and synthesize their hybrid compounds and explore their antiproliferative activity against a panel of six cancer cell lines and two normal cell lines. Compounds 5a–d displayed significant antiproliferative activities against all the cancer cell lines tested, and IC50 values were in the range of 5.2–22.2 μM against MDA-MB-231 cancer cells, while they were minimally cytotoxic to the HEK-293 and LLC-PK1 normal cell lines. The IC50 values of 5a–d …

Association Of Environmental Pollutants Exposure With Pulmonary Fibrosis: A Mini Review Of Molecular Mechanism Mediated, Soni Siswanto, Bantari W.K. Wardhani Apr 2022

Association Of Environmental Pollutants Exposure With Pulmonary Fibrosis: A Mini Review Of Molecular Mechanism Mediated, Soni Siswanto, Bantari W.K. Wardhani

Pharmaceutical Sciences and Research

Pulmonary fibrosis is a specific form of chronic progressive interstitial lung disease. Deposition of extracellular matrix, mainly collagen, is the pathogenic characteristic of pulmonary fibrosis. Many reports show that environmental pollutants, particularly asbestos, silica, mercury, cadmium, and benzo(a)pyrene, are contributed in the etiology of lung injury and a risk factor in the development of idiopathic pulmonary fibrosis (IPF) in humans. Based on its physicochemical properties, environmental pollutant-induced pulmonary fibrosis can be developed after a particular type or dose of exposure. To date, some studies have focused on variant pollutants that are induced. However, the molecular mechanism of various pollutants to …

Cyclic dipeptides, also know as diketopiperazines (DKP), the simplest cyclic forms of peptides widespread in nature, are unsurpassed in their structural and bio-functional diversity. DKPs, especially those containing proline, due to their unique features such as, inter alia, extra-rigid conformation, high resistance to enzyme degradation, increased cell permeability, and expandable ability to bind a diverse of targets with better affinity, have emerged in the last years as biologically pre-validated platforms for the drug discovery. Recent advances have revealed their enormous potential in the development of next-generation theranostics, smart delivery systems, and biomaterials. Here, we present an updated review on the …

Pharmacological Characterization Of Novel Serotonin Transporter Inhibitors Identified Through Computational Structure-Based Virtual Screening, Michael Wasko Dec 2020

Pharmacological Characterization Of Novel Serotonin Transporter Inhibitors Identified Through Computational Structure-Based Virtual Screening, Michael Wasko

Electronic Theses and Dissertations

Depression is a mental health disorder affecting greater than 350 million people worldwide with roughly 7% of the United States population diagnosed as of 2017. The selective serotonin reuptake inhibitors (SSRIs) have been the mainstay of pharmacotherapies for depression for the last 40 years. The SSRIs target the serotonin transporter (SERT), a monoamine transporter (MAT) responsible for terminating serotonergic neurotransmission. The SSRIs are not perfect therapeutics and suffer from delayed response times, inconsistent efficacy among patients, and often produce intolerable side effects. Therefore, a strong need exists to develop new antidepressants that are more efficacious and have fewer adverse effects. …

Phosphatidylinositol 3-Kinase (Pi3k) As A Therapeutic Target In Nsclc, Christopher W. Stamatkin Jan 2014

Phosphatidylinositol 3-Kinase (Pi3k) As A Therapeutic Target In Nsclc, Christopher W. Stamatkin

Theses and Dissertations--Pharmacy

Deregulated activation of phosphatidylinositol 3-kinase (PI3K) pathway is central to many human malignancies. The functions of this pathway are critical for normal cell metabolism, proliferation, and survival. In lung cancers, the PI3K pathway activity is often aberrantly driven by multiple mutations, including EGFR, KRAS, and PIK3CA. Molecules targeting the PI3K pathway are intensely investigated as potential anti-cancer agents. Although inhibitors of the pathway are currently in clinical trials, rational and targeted use of these compounds, alone or in combination, requires an understanding of isoform-specific activity in context. We sought to identify class IA PI3K enzyme (p110a/PIK3CA, p110b/PIK3CB, p110d/PIK3CD) activities using …
