Considering the importance to find highly active anticancer agents, we investigated the synthesis and cytotoxic activity of twenty seven 2,4-disubstituted quinazoline derivatives. The cytotoxicity of compounds 1-27 was tested in SRB assays employing five different human tumor cell lines showing four compounds, 2, 9, 16 and 26, being highly cytotoxic with IC50 values ranging between 2.1 and 14.3 µM. The possible mode of action of compounds, 2, 9, 16 and 26, and the taxol binding site of the protein tubulin, an important goal for antimitotic drugs, was also studied by molecular docking followed by an investigation of the effects of compounds 9 and 16 on the polymerization of tubulin using a commercially available assay kit...

OBJECTIVE: Many experiments have revealed the anti-tumor activity of spiro-quinazolinone derivatives on different cell types. Exposing KG1-a cells to N-(4- tert- butyl- 4'- oxo- 1'H- spiro [cyclohexane- 1, 2'- quinazoline]- 3'(4'H)- yl)- 4- methyl benzenesulfonamide (4t-CHQ), as an active sub-component of spiro-quinazolinone benzenesulfonamides, the experiment investigated the possible mechanisms that manifest the role of 4t-CHQ in leukemic KG1-a progenitor cells. Mechanistically, the inhibitory effects of 4t-CHQ on KG1-a cells emerges from its madulating function on expression of Bax/Bcl2 and suvinin proteins...

Lung cancer is one of the leading cause of cancer death worldwide, the most common histological type of lung cancer is non-small cell lung cancer (NSCLC), whose occurrence and development is closely related to the mutation and amplification of epidermal growth factor receptors (EGFR). Currently , a series of targeted drugs were developed on the inhibition of EGFR,such as epidermal growth factor receptor-tyrosine kinase inhibitor(EGFR-TKI) and monoclonal antibody (McAb). These drugs have been widely used in clinic practices...

BACKGROUND: Breast Cancer (BC) is the second most common cause of cancer related deaths in women. Due to severe side effects and multidrug resistance, current therapies like hormonal therapy, surgery, radiotherapy and chemotherapy become ineffective. Also, the existing drugs for BC treatment are associated with several drawbacks such as poor oral bioavailability, non-selectivity and poor pharmacodynamics properties. Therefore, there is an urgent need for the development of more effective and safer anti BC agents...

Conventional drug discovery is a time overwhelming and expensive expedition with super less clinical preference achievement proportion intended for breast cancer therapy. Even if numerous novel approaches to conformation of anti-cancer drugs have been introduced for breast cancer therapy, they have up till now to be implemented in clinical practice. This tempting strategy, facilitate remarkable chance to take entire benefit of existing drugs. Despite drug repurposing significantly decrease the investigational period and cost, it has got many objection and issues...

Background& Objective: Nitrogen mustard derivatives form one of the major class of the anti-cancer agents according to the USFDA approved drugs. These are polyfunctional alkylating agents which are distinguished by a unique mechanism of adduct formation with the DNA that involves a cross-linking between guanine N-7 of one strand of DNA with the other. The generated cross-linking is irreversible and leads to cell apoptosis. Thus, there is an upsurge in the interest to explore this class of anticancer alkylating agents...

BACKGROUND: Multi Drug Resistance (MDR) is the phenomenon that cancers develop resistance to majority of chemotherapy drugs and is a serious obstacle to the treatment for hepatocellular carcinoma (HCC). Polo-Like Kinase 1 (PLK1) is a serine/threonine kinase associated with tumor growth and clinical prognosis in HCC and BI2536 is its potent inhibitor with IC50 of 0.83 nM. AIMS: To test whether the down-regulation of PLK1 by its inhibitor BI2536 would have beneficial effects on the reversal of MDR in HCC cells...

In recent times, we have reported the design and in silico studies of 52 hydroxamic acid derivatives bearing multi-substituent heteroaromatic rings with chiral amine linker as isoform selective histone deacetylase 8 inhibitors (HDAC8i). Wherein, the report suggested that the presence of chiral amine is a prerequisite to occupy the second binding site of HDAC8. Based on these preliminary results, five compounds were shortlisted and synthesized by microwave assisted approach and high yielding synthetic protocol...

Skin photoaging, skin inflammation and skin cancer are related with excessive exposure to solar ultraviolet light (solar-UV). PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK), a member of the serine/threonine protein kinase, which regulates the signaling cascades of p38 mitogen-activated protein kinase (p38 MAPK) and extracellular signal regulated kinase 1/2 (ERK1/2). PBK/TOPK plays a significant role in solar-UV-induced cutaneous basal cell carcinoma (cutaneous-BCC), and targeting PBK/TOPK can be supposed to treat and prevent cutaneous-BCC...
