Multiple drug resistance (MDR) remains a major clinical challenge for cancer treatment. P-glycoprotein is the major contributor and they exceed their role in the chemotherapy resistance of most of the malignancies. Attempts in several preclinical and clinical studies to reverse the MDR phenomenon by
Thirty-one 2'-hydroxychalcones were prepared via solid-phase synthesis by base-catalyzed aldol condensation of substituted 2'-hydroxyacetophenones and benzaldehydes. Chalcones were tested for their growth inhibitory activity in three human tumor cell lines (MCF-7, NCI-H460 and A375-C5) using the SRB
p-Hydroxyacetophenone (HAP) is a crucial chemical compound present in plants of the genus Artemisia, which are used in traditional therapies for treating jaundice, hepatitis, and inflammatory diseases. Nevertheless, the bioactivity of HAP remains to be identified in order to prove its importance in
Vanadium compounds are well known for their therapeutic interventions against several diseases. Various biochemical attributes of vanadium complexes inspired us to evaluate the cancer cell killing efficacy of the vanadium complex, viz., vanadyl N-(2-hydroxyacetophenone) glycinate [VO(NG)2].
BACKGROUND
The tumor microenvironment (TME) renders tumor cells more resistant to chemotherapy. However, effective immunomodulators for cancer therapy are still elusive. We hypothesized that Mn-N-(2-hydroxyacetophenone) glycinate (MnNG), reported to be an antitumor agent, can modulate the
Induction of undesired toxicity and emergence of multidrug resistance (MDR) are the major obstacles for cancer treatment. Moreover, aggressive cancers are less sensitive towards existing chemotherapeutics. Therefore, selective targeting of cancers without inducing undesired side effects and
Chemotherapy is central to current treatment modality especially for advanced and metastatic colorectal and breast cancers. Targeting the key molecular events of the neoplastic cells may open a possibility to treat cancer. Although some improvements in understanding of colorectal and breast cancer
Eight Ti(iv) compounds 1-8, of the type [Ti(Ln)2] where Ln is a variously substituted dianionic tridentate acylhydrazone, were synthesized by reacting the appropriate hydrazide with 2-hydroxybenzaldehyde or 2'-hydroxyacetophenone and titanium(iv) tetra(isopropoxide) in a 2 : 2 : 1 molar ratio. The
The constituents of cape aloe were investigated after a preliminary screening of the growth-inhibiting effect on Ehrlich ascites tumor cells (EATC) of several extracts of this plant. Ten compounds were isolated from the dichloromethane (CH(2)Cl(2)) extract that showed the strongest activity, and
Polydimethylsiloxane (PDMS) is widely used as a cell culture platform to produce micro- and nano-technology based microdevices. However, the native PDMS surface is not suitable for cell adhesion and is always subject to bacterial pollution and cancer cell invasion. Coating the PDMS surface with
One of the major reasons for multidrug resistance (MDR) in cancer is the overexpression of P-glycoprotein (P-gp, ABCB1), a drug efflux pump. A novel copper complex, namely, copper (II) N-(2-hydroxyacetophenone) glycinate (CuNG) previously synthesized and characterized by the authors had been tested
Rosemary and sage are common spices used in food. In our recent search of cancer chemopreventive agents from spices, the alcohol extracts of rosemary and sage showed strong antumorigenic activities. Rosemary and sage extracts contain active antioxidative factors such as phenolic diterpenes,
To explore the regulatory effect and relevant mechanisms of the fraction of Hedyotis diffusa and Scutellaria barbata herb couple(YDW11) on polarization of macrophage between M1/M2 phenotypes.RAW264.7 cells were induced with LPS/IFN-γ or IL-4/IL-13 to establish M1 or M2 macrophage cell model. MTT
The root of Cynanchum wilfordii (C. wilfordii) contains several biologically active compounds which have been used as traditional medicines in Asia. In the present study, we evaluated the anti-inflammatory effects of an ethanol root extract of C. wilfordii (CWE) on tumor necrosis factor
The aim of this study was to investigate the possible analgesic and anti-inflammatory mechanisms of the ethanolic extract of A. morrisonensis Hayata (AM(EtOH)). Two models were employed for evaluation of the analgesic effects: acetic acid-induced writhing response and formalin-induced paw licking.
