In order to be prequalified, medicines must meet WHO-specified standards for quality, safety and efficacy. PQP is supported by vari- ous United Nations agencies (e.g., UNAIDS, UNICEF, UNFPA) and the World Bank. WHO prequalification of medicines is a multi-step process whereby a manufacturer submits extensive information that is then evaluated by a WHO assessment team with respect to product quality, safety and efficacy, site(s) of manufacture and any clinical studies that may have been carried out during development. Products that successfully pass PQP evaluation are listed on the WHO List of Prequalified Medici- nal Products (see: http://www.who.int/prequal). This list provides UN agencies with a single source of reference for quality-assured priority medicines and is also used by a variety of entities, both country-specific and international, that purchase medicines in bulk quantities. The Prequalification of Medicines Programme has conducted a comprehensive sur- vey among pharmaceutical manufacturers to assess its level of service. PQP as- sessment and inspection activities reflect those carried out by national regulatory authorities before granting marketing authorization (registration) for a medicine. The assessment review was therefore designed to maximize the diagnostic capability of the survey: to measure both the level of service provided by PQP and the levels of service expected from regulatory authorities by manufacturers. The survey included items relevant to the assessment of product dossiers and on-site inspections of manu- facturing facilities in a way that separated service design (the service process) from service delivery (or the “people” aspects of service). The results of this survey pro- vide direction for improvements to the current Programme and have implications for future strategic development. The survey organization recommended that WHO undertake a process optimization review In administering the Prequalification of with respect to PQP – an exercise that Medicines Programme (PQP), WHO would include feedback from manufactur- interacts with a number of stakeholder ers with experience of WHO prequalifica- groups and organizations whose objec- tion of medicines. tives are dependent upon, or related to, WHO prequalification of medicines: To provide guidance in developing a manufacturers, government agencies survey of manufacturers, implementing (including national and regional medi- the survey and analysing the results, cines regulatory authorities) and donor PQP retained the services of a market organizations.

Estrogen receptor status is an important prognostic factor and endocrine therapy is the choice of rst-line treatment in ER-positive breast cancer. However, most tumors develop resistance to endocrine therapy. Here we demonstrate that BH3 proling technology, in particular dynamic BH3 proling can predict the response to endocrine therapy agents as well as development of acquired resistance in breast cancer cells independent of estrogen receptor status. Immunouorescence analysis and subcellular fractionation experiments revealed distinct ER-α and ER-β subcellular localization patterns in breast cancer cells, including mitochondrial localization of both receptor subtypes. shRNA-mediated depletion of ER-β in breast cancer cells led to resistance to endocrine therapy agents and selective reconstitution of ER-β in mitochondria restored sensitivity. Notably, mitochondria-targeted ER-α did not restore sensitivity, even conferred further resistance to endocrine therapy agents.

Estrogen receptor status is an important prognostic factor and endocrine therapy is the choice of first-line treatment in ER-positive breast cancer. However, most tumors develop resistance to endocrine therapy. Here we demonstrate that BH3 profiling technology, in particular, dynamic BH3 profiling can predict the response to endocrine therapy agents as well as the development of acquired resistance in breast cancer cells independent of estrogen receptor status. Immunofluorescence analysis and subcellular fractionation experiments revealed distinct ER-α and ER-β subcellular localization patterns in breast cancer cells, including mitochondrial localization of both receptor subtypes. shRNA-mediated depletion of ER-β in breast cancer cells led to resistance to endocrine therapy agents and selective reconstitution of ER-β in mitochondria restored sensitivity. Notably, mitochondria-targeted ER-α did not restore sensitivity, even conferred further resistance to endocrine therapy agents. In addition, expressing mitochondria-targeted ER-β in breast cancer cells resulted in decreased mitochondrial respiration alongside increased total ROS and mitochondrial superoxide production. Furthermore, our data demonstrated that mitochondrial ER-β can be successfully targeted by the selective ER-β agonist Erteberel. Thus, our findings provide novel findings on mitochondrial estrogen signaling in breast cancer cells and suggest the implementation of the dynamic BH3 technique as a tool to predict acquired endocrine therapy resistance.

  • In Silico Prediction of Heliannuol A, B, C, D, and E Compounds on Estrogen Receptor Β Agonists
    Indonesian Journal of Cancer Chemoprevention, February 2021 ISSN: 2088–0197 e-ISSN: 2355-8989 In Silico Prediction of Heliannuol A, B, C, D, and E Compounds on Estrogen Receptor β Agonists Roihatul Mutiah, Alif Firman Firdausy, Yen Yen Ari Indrawijaya, Hibbatullah* Department of Pharmacy, Faculty of Medical and Health Sciences, Maulana Malik Ibrahim State Islamic University of Malang, Indonesia Abstract Heliannuols has a benzoxepine ring that produces anticancer activity by the inhibition mechanism of phosphoinositide 3 kinases (PI3K). Heliannuols are a compound that can be found in the leaves of sunflower Helianthus( annuus L.). The purpose of this study is to predict interactions, toxicity, physicochemical, and pharmacokinetics of Heliannuol A, B, C, D, and E based in silico as candidate anticancer drugs. Estrogen receptor beta (ERβ) is a new potential therapy for glioma with an antiproliferative effect. Ligands agonist ERβ have the potential activity to inhibit the proliferation of glioma cells and the discovery of this ligand has opened new therapy through the ERβ to prolong survival in cancer patients. Prediction of physicochemical properties based on Lipinski rules and penetrate in the blood-brain barrier. Receptor validation shows that 2I0G(A) has a smaller RMSD value than 2I0G(B), receptor validation is valid if the RMSD value less than 2. The result of molecular docking shows that Heliannuols comply with Lipinski rules and have low toxicity. Heliannuols also have a similar amino acid with comparison drug (Erteberel), but the rerank score of Erteberel still lower than Heliannuols. Keywords: Helianthus annuus, Heliannuols, estrogen receptor β (ERβ), in silico, toxicity.

Allergan plc, USA Abstract Prostanoid receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Prostanoid Receptors [659]) are activated by the endogenous ligands prostaglandins PGD2, PGE1, PGE2 , PGF2α, PGH2, prostacyclin [PGI2] and thromboxane A2. Measurement of the potency of PGI2 and thromboxane A2 is hampered by their instability in physiological salt solution; they are often replaced by cicaprost and U46619, respectively, in receptor characterization studies.
