The aldo-keto reductase 1C3 (AKR1C3) enzyme is considered an attractive target in Castration Resistant Prostate Cancer (CRPC) because of its role in the biosynthesis of androgens. Flufenamic acid, a non-selective AKR1C3 inhibitor, has previously been subjected to bioisosteric modulation to give rise to a series of compounds with the hydroxytriazole core. In this work, the hit compound of the previous series has been modulated further, and new, more potent, and selective derivatives have been obtained.

Background: Pyrrolo[2,3-d]pyrimidines have been recently reported to have anticancer activities through inhibition of different targets such as, Epidermal Growth Factor Receptor (EGFR) tyrosine kinase, Janus Kinase (JAK), mitotic checkpoint protein kinase (Mps1), carbonic anhydrase, MDM-2. On the other hand, aryl urea moieties which are found in some tyrosine kinase inhibitors such as Sorafenib and Linifanib have aroused recent attention as responsible for anticancer activities. The aims of this paper are to synthesize pyrrolo[ 2,3-d]pyrimidine derivatives containing urea moiety and evaluate their anti-cancer activity against human lung cancer cell line (A549), prostate cancer cell line (PC3), human colon cancer cell line (SW480) and human breast cancer cell line (MCF-7).

Background: Matrix metalloproteinases are known as extracellular matrix degrading enzymes and have important role on tumor progression.

Objective: This study reports the effects of 1,3,5-trisubstituted indole derivatives on cytotoxicity, apoptosis and MMP- 2/MMP-9 mRNA expression of MCF-7 human breast carcinoma cells.

Method: The cytotoxic effects of the compounds on MCF-7 cells were performed by MTT test, and cell proliferation was determined via BrdU incorporation.

Background: Oxidative stress has been implicated in aging and in a variety of diseases affecting the nervous, respiratory, cardiovascular and gastrointestinal system in humans. Reactive oxygen species (ROS) have been associated with mechanisms to activate kinases, such as protein tyrosine kinases, which may initiate malignant transformation. Significant evidences of the activation of protein kinases by oxidative stress brought increased attention to the role of antioxidants in these mechanisms.

Hyaluronidase inhibitors are of potential therapeutic value for the treatment of a variety of diseases, such as cancer, arthrosis, or bacterial infections. Potent and selective hyaluronidase inhibitors are not known so far, and current approaches to the development of hyaluronidase inhibitors are limited. Elevated levels of hyaluronan (HA) are connected with most malignant tumours.
