Application of chemotherapy in cancerous children leads to reduction of immune system efficiency. Therefore, these children are prone to various infectious diseases. The excessive use of antibiotics can bring about antibiotic resistant strains. Hence, it is essential to investigate new therapies for this problem. On the other hand, the emergence of resistance against multiple drugs is a major p...

In the present study, the hydrophobicity of a 26-residuea-helical peptide (peptideP)was altered to study the effects of peptide hydrophobicity on the mechanism of action of cationic anticancer peptides. Hydrophobicity of the nonpolar face of the peptideswas shown to correlate with peptide helicity. The self-association ability of peptides in aqueous environment, determined by the reversed-phase...

Cancer is the second leading cause of death worldwide. There always a huge demand for novel anticancer. New series pyrazole, pyridine, thiazole derivatives containing sulfonamide moiety were prepared and screened their antitumor activity against breast cancer cell line (MCF-7). The results this investigation revealed that compounds 3 8 had significant anticancer MCF-7 with IC50 values 19.2 14.2...

Objective(s):This study aims at exploring cytotoxic activity of different peptides derived from VSVG protein against MCF-7 and MDA-MB-231 breast cancer cell lines and human embryonic kidney normal cell (HEK 293).    Materials and Methods: The ANTICP web server was used to predict anticancer peptides. The cytotoxic activity of peptides with high score (P26, P7) and low score (P19) was examined b...

The effect of anticancer drugs on invasive capacity of Lu 135 human small-cell lung cancer cells was studied in vitro. the invasive capacity decreased in a dose-dependent manner when tumor cells were treated with the anticancer drugs cisplatin and etopside. The inhibition of tumor cell invasion was almost parallel with the inhibition of tumor cell growth. The anticancer drugs also suppressed tu...

Introduction:  Microalgae  are  known  for  their  bioactive  compounds  with  potential applications as antimicrobial, antiaging, and anticancer activities. Spirulina platensis (S. platensis) is a filamentous and photosynthetic microorganism that has 25 kinds of vitamins and minerals that contain many compounds with biotic activity such as alkaloids, phenolic compounds, terpenoids, and saponin...

Andrographolide (Andro) has been reported to have anticancer activity in multiple types of cancer due to its capacity to inactivate NF-κB pathway. Previous studies showed the therapeutic potential of targeting NF-κB pathway in nasopharyngeal carcinoma (NPC). However, the anticancer activity of Andro in NPC has not been reported. In this study, we defined the anticancer effects of Andro in NPC a...

an efficient synthesis of polyhydroquinoline derivatives is achieved via hantzsch condensation reaction between aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of catalytic amount of sfhs in ethanol. this method gives remarkable advantages such as shorter reaction time, simple workup procedure and good to excellent yields. furthermore the catalyst can be recovered c...

Breast cancer is one of the major health problems among women in both developed and developing countries. The objective of the present investigation is focused on the DPPH Radical Scavenging Activity and anticancer effect of the methanolic extract of Moringa concanensis Nimmo leaves against Breast cancer (MCF-7) cell line. The study was facilitated by collecting the plant sample and subjected t...

the biological activity and composition of the essential oil of sclerorhachis leptoclada rech. an endemic species from northeast of iran was studied. the essential oil was isolated from the aerial flowering parts of the plant and analyzed by gc and gc-ms. fifty-four compounds accounting for 95.9% of the total oil were characterized. the main constituents were (e)-nerolidol (14.5%), terpinen-4-o...
