Drug Development for PCGF2 Protein, Involved in Formation of Human Breast Cancer by Polyphenols and Their Derivatives Extracted from Cowania maxicana. International Journal of Pharmacy and Chemistry. Vol. 3, No. 6, 2017, pp. 77-81. doi: 10.11648/j.ijpc.20170306.12 Received: May 28, 2017; Accepted: October 8, 2017; Published: November 15, 2017 Abstract: In women, the most commonly found cancer is breast cancer. PCGF2 (polycomb group RING finger protein 2) was found to be one of the reasons that cause breast carcinoma in women. Ring finger protein causes formation of multiprotein complexes and mediates interactions between different proteins. The polyphenols, extracted from Cowania maxicana and their derivatives were found to have anti proliferative activities. They showed greater efficiency and specificity towards the target protein PCGF2 (polycomb group RING finger protein 2). Keywords: Breast Cancer, PCGF2, Polyphenols, Cowania maxicana, Pedunculagin 1. Introduction A tumor that is present in the area of breast in the humans is called adenocarcinoma. Breast cancer is one of the most common cancers occurring in human and cover 18% of all cancers and nearly 1 in 3 cancers diagnosed among women in the United States (DeSantis et al., 2011). There are many methods to treat cancer e.g. surgery, radiation therapy and chemotherapy. The clinical way of a patient having breast carcinoma stays tricky to predict, as tumors of apparently homogenous morphological characteristics still differ in response to therapy and have different results (Alizadeh et al., 2001; Rakha et al., 2007). The clinical course of a patient with breast carcinoma remains difficult to predict, as tumors of apparently homogenous morphological characteristics still vary in response to therapy and have divergent outcomes. Chemo prevention is another method to treat cancer. Using natural or manmade products to treat cancers is called cancer. It is considered along, proficient and reversible process to treat invasive and multistage cancers (Kuo et al., 2005). Chemoprevention has been studied a lot in recent years. Cowania mexicana (rosaceae) is found in North America. Its leaves and branches showed antitumor activity by strongly inhibiting the PCGF2 protein (also known as ring finger protein 110) involved in formation of breast adenocarcinoma. This plant has other medicinal properties. It has been used against respiratory disease and cough. Mixed extract of herbs or plants might contain different chemo preventive chemotherapeutic compounds with more than one mechanism of action (Hu et al., 2002). Recent studies show that rosaceous plants have an abundant amount of polyphenols that have various biological activities. I have examined the polyphenols and their derivatives of this plant. In this paper I have characterized polyphenols extracted from Cowania mexicana and its derivates and checked their antitumor activity by examining their inhibitory effect on PCGF2. Phenotypic behavior of cancer cells is not only controlled by cell autonomous signals, but it is also affected by adjoining stormal cells (Barbarestani et al., 2006). Ring finger is a pattern of conserved histidines and cysteines that synchronize two zinc atoms in a cross-brace system, a ligation scheme distinct from those of classical zing finger 1
