Stereochemistry has evinced the importance of many chiral drugs with respect to drug designing and development. A literature review was conducted for several chiral drugs involving pharmacokinetic and pharmacodynamic parameters of their enantiomers along with their uses in certain diseased conditions. This article mainly includes the pharmacological profile review of some chiral drugs and the aspects due to Read More

In the field of heterocyclic medicinal chemistry, especially five-membered ring structures containing a nitrogen atom, imidazole core is an imperative aromatic heterocycle which is usually present in naturally occurring products and synthetic bioactive molecules. The occurrence of imidazole moiety in therapeutic compounds may be beneficial in terms of improving water-soluble properties due to its two nitrogen ato Read More

Background: Cancer is a complex disease involving genetic and epigenetic alteration that allows cells to escape normal homeostasis. Kinases play a crucial role in signaling pathways that regulate cell functions. Deregulation of kinases leads to a variety of pathological changes, activating cancer cell proliferation and metastases. The molecular mechanism of cancer is complex and the dysregulation of tyrosine kinases like Anaplas Read More

Background: Non-Hodgkin's lymphomas (NHL), derived from B- or T-cell, consist of a heterogeneous group of malignant lymphoproliferative disorders. Knockdown of Casein kinase 2 interacting protein-1 (CKIP-1) in NHL promoted cell proliferation and inhibited apoptosis via enhancing phosphorylated Protein Kinase B (PKB or AKT) expression. Statins are the class of drugs that inhibit the ratelimiting step of the mevalona Read More

Background: Fenchone is a natural monoterpene abundantly present in fennel essential oil. It is known for its wound healing properties but its other biological activities are less explored. Methods: We used an in silico structural similarity searching approache to identify various biological activities of fenchone. The identified biological activities of fenchone (purchased from Sigma Aldrich) were validated by conducting DPPH free rad Read More

Background: In spite of current progress in treatment methods, cancer is a major source of morbidity and death rate all over the world. Traditional chemotherapeutic agents aim to divide cancerous cells, are often associated with deleterious side effects to healthy cells and tissues. Host defense peptides Cecropin A and B obtained from insects are capable to lyses various types of human cancer cells at peptide concentrations whi Read More

Background: Capsaicin is an active alkaloid /principal component of red pepper responsible for the pungency of chili pepper. Capsaicin by changing the intracellular redox homeostasis regulate a variety of signaling pathways ultimately producing a divergent cellular outcome. Several reports showed the potential of capsaicin against cancer metastasis, however unexplored molecular mechanism is still an active part of the res Read More

Background: Detailed photochemical and photocytotoxicity studies of two new porphyrins: 5,10,15,20-meso-tetrakis-(4-acetoxy-3-methoxyphenyl) porphyrin (P2.1) and 5-(4-hydroxy-3- methoxyphenyl)-10,15,20-tris-(4-acetoxy-3-methoxyphenyl)porphyrin (P2.2) are reported, as potential candidates for theranostics. For powdered samples of P2.1 and P2.2 adsorbed onto a powdered biocompatible substrate, polyethylene g Read More

Background: Malaria is still a dangerous disease that impacts specifically Africa, Asia, and Latin America. The development of therapies to overcome the parasite infection is an important challenge nowadays. The medicine primaquine (PQ) is used in the treatment, although several side effects and low oral bioavailability are reported. Objective: This work focused on the preparation and characterization of a complex bet Read More

Background: P-21 activating kinase 4 (PAK4) is implicated in poor prognosis of many human tumors, particularly in Triple Negative Breast Cancer (TNBC) progression. Studies have revealed the crucial role of PAK4 in cell proliferation, anchorage-independent growth and cell migration among other hallmarks of cancer. Thus, PAK4 is an attractive target for anti-TNBC drug design and development. In our research, we used in sili Read More

Introduction: Finding non-systemic antipyretic option in cancer patients who simultaneously receive several other drugs seems be logical. This study was designed to evaluate complementary therapy with Viola odorata L. oil for fever control in febrile neutropenic children. Methods and Materials: In a randomized placebo controlled clinical trial, 41 febrile children were divided into two groups. Children in the active drug group recei Read More

Background: Rheumatoid Arthritis (RA) is a complex disease involving an unknown number of genes, and affecting a large number of organs, tissues, and sites across the body. It is affecting approximately 1% of the population worldwide. The safety and therapeutic efficacy of β-D-mannuronic acid (M2000) as a novel NSAID with immunosuppressive property has been demonstrated under in vitro, in vivo examinatio Read More

Background and Objective: Infertility is a major problem in medical sciences. Despite recent advances in diagnosing and treatment of infertility, it is still one of the most important medical problems. The aim of this study is to review the role of the parsnip (Pastinaca sativa L), a proposed remedy as to a fertile agent in the viewpoint of Iranian traditional medicine (ITM) and review the evidence in the conventional medicine. Method Read More

Background: The key issue in the development of novel antimicrobials is a rapid expansion of new bacterial strains resistant to current antibiotics. Indeed, World Health Organization has reported that bacteria commonly causing infections in hospitals and in the community, e.g. E. Coli, K. pneumoniae and S. aureus, have high resistance vs the last generations of cephalosporins, carbapenems and fluoroquinolones. During t Read More

Background: Recent studies have observed overexpression of histone deacetylase 7 (HDAC7) and overactivity of extracellular signal-regulated kinases 1/2 (ERK1/2) in many tumors; therefore, pharmacological interventions to inhibit overexpression of HDAC7 and overactivity of ERK1/2 in cancerous cells holds great promise in cancer treatment. The promising anticancer properties of artemisinin and artemisinin-derivatives Read More

Background: Zebrafish have similar hepatic anatomy and cellular architecture just like mammals. Therefore, a number of investigators are using zebrafish to study liver pathologies. However, the evaluation model specific to liver toxicities in zebra fish was not clearly stated earlier. Aims and Objectives: The present study was designed to develop a model of embryonic liver toxicity using dexamethasone (DEXA, 0-20 μM) as a s Read More

Cyclin Dependent Kinases-2 (CDK2) are members of serine/threonine protein kinases family. They play an important role in the regulation events of the eukaryotic cell division cycle, especially during the G1 to S phase transition. Experimental evidence indicate that excessive expression of CDK2s should cause abnormal cell cycle regulation. Therefore, since a long time, CDK2s have been considered potential therapeutic targets for Read More
