Amg 336 Synthesis

However, the majority of known anti-cancer drugs target normal cells as well. Methotrexate, formerly known as amethopterin, is an antimetabolite used in the treatment of some forms of cancer (Shacter and Law, 1956). It inhibits the function of dihydrofolate reductase (DHFR) by tightly binding to the enzyme. Following this slow interaction between methotrexate and DHFR, an enzyme-NADPH-inhibitor complex is formed (Stone et al., 1984). Therein, DHFR is rendered unable to catalyze the NADPH-dependent reduction of dihydrofolate to tetrahydrofolate (Anderson, 2017). Tetrahydrofolate is an important methyl group shuttle in the de novo synthesis of purine and pyrimidine nucleotides and some amino acids (Barbara and Hiroshi, 2002). Therefore, eliminating it from cells is a good therapeutic strategy against cancer cells, as it would limit the de novo synthesis of purines and pyrimidines (Lane and Fan, 2015). Inhibiting the function of DHFR by its competitive inhibitor methotrexate is one such good therapeutic strategy, as it would disable DHFR from converting dihydrofolate into tetrahydrofolate. However, some types of cancer cells had acquired some forms of resistance against methotrexate (Hans et al., 2011). Equally important, methotrexate should be administered in well established low doses, because it affects

The two essays that I choose for the synthesis essay are Parkinson’s Alley by Joy Horowitz and The Environmental Issue from Hell: Global Warming Is the Great Moral Crisis of Our Time by Bill Mckibben. Parkinson’s Alley is about residents in California’s Central Valley town of Visalia who have been diagnosed with Parkinson’s. This part of California has the highest number of people diagnosed with the neurodegenerative disease. The pesticides that are used in the surrounding farms seeps into the water that the residents use every day, causing them to get the disease. The Environmental Issue from Hell: Global Warming Is the Great Moral Crisis of Our Time is about how global warming is a moral crisis that, if not combated

This lab could have contained errors. The errors could have happened when performing the lab. Some of the possible errors in this lab are:

In vitro: Crizotinib (PF-02341066) potently inhibited c-Met phosphorylation and c-Met-dependent proliferation, migration, or invasion of human tumor cells in vitro. In addition, crizotinib potently inhibited HGF-stimulated endothelial cell survival or invasion and serum-stimulated tubulogenesis in vitro, suggesting that crizotinib also exhibits antiangiogenic properties [1].

Design: This was a Phase 1 trial to determine the MTD of ceritinib in adult patients with tumors harboring a genetic alteration in ALK. Secondary objectives were to characterize the safety and side-effect profile, pharmacokinetic profile, and antitumor activity of ceritinib.

MMP-9 is a matrixin, a class of enzymes that belong to the zinc-metalloproteinases family involved in the degradation of the extracellular matrix and have an important role in cancer progression. VEGF is a protein produced by cells that stimulates angiogenesis. It restores the oxygen supply to cells when blood circulation is inadequate and also similar to MMP-9 causes to cancer

After decades of experience, medical research is now focusing on slowing or preventing the progression of this cancer. By learning all the biochemical pathways involved in the initiation, progression, and proliferation of cancer, scientists hope that they can find ways to change how cancer develops.

GM1 is a ganglioside that impacts neuronal plasticity, repair mechanisms, and the release of neurotrophins in the brain. GM1 promotes neuronal growth and survival by modulating tyrosine kinase receptors for neurotrophic factors. GM1’s neurotrophic action is exerted on dopaminergic neurons by interacting with the GDNF receptor complex, Ret tyrosine kinase, and GFR alpha-1

The purpose of this lab is to find the oxidation state of manganese for the synthesis of manganese (?) chloride, and to complete the naming of the compound. The discovery of the charge of manganese in the ionic compound will be used to further the analysis of the reaction. The lab requires performing the chemical reaction of synthesizing manganese metal and hydrochloric acid. The laboratory techniques required to find the oxidation state will include qualitative observation, collecting quantitative data, gravimetric analysis, unit conversions, and stoichiometry.

The exposure of skin to ultraviolet B (UVB) radiation has a destructive effect on keratinocytes by causing DNA damage that can subsequently lead to malignant transformation. Cellular defense mechanisms against this injury begin with the immediate UVB induced death of damaged cells. In less severely affected cells, cellcycle progression can be blocked and DNA damage can be repaired through nucleotideexcision repair (NER). If repair is successful and cells have not suffered irreversible damage, they will survive.

GDC-0879 is a potent, selective and orally bioavailable RAF small-molecule inhibitor. GDC-0879 effectively inhibited phospho-ERK with an IC50 values of 63 nmol/L and inhibited cellular viability of BRAF-mutant Malme3M cells with an EC50 values of 0.75 µmol/L. Moreover, there was a strong correlation between activating mutations of the BRAF oncogene and GDC-0879

The number of people diagnosed with skin diseases from UV radiation continues to escalate. Therefore, striving to find alternative protection method against UV radiation is critical. This study used salicylic acid as a non-topical protection against UVB light. Organic compounds with benzene rings absorb UV light based on the different ring structures. The chemical, salicylic acid, contains a benzene ring that has absorbing properties of UVB light. The purpose of this experiment was to test if a thin or thick layer of 2% salicylic acid will be more effective against UVB radiation. If the thickness of the salicylic acid affects UVB protection then the amount of yeast colonies that survive under the thicker treatment will be statistically significant.

De-Methylation is the removal of methyl groups from DNA all together, which would lead to active corresponding cancer genes thus enhancing the threat. So far it is clear to scientists that Methylation of DNA directly influences gene expression, cancer being abnormal in expression patterns. In repressing or stimulating methylation in the cell, research indicates that transcription of cancer cells can be repressed which could lead to cancer gene arrest. This drug would be a good candidate for an anti-cancer drug because if we’re able to correct the DNA methylation in cancer cells, they would be able to behave normally. Methylation inhibitors could assist in reactivating epigenetically silenced genes in cancer and reverse aberrant DNA methylation restoring regular gene functions and tumor cell growth arrest.

Imatinib mesylate is a protein tyrosine kinase (RTK) inhibitor that exhibits high specificity and potency for ABL, c-kit, and PDGF receptors, which often harbor activating mutations and are typically mutually exclusive of each other and within specific cancer types.2 The compound has been approved as a targeted chemotherapy for Philadelphia chromosome positive chronic and acute myeloid leukemia (Ph+ CML and AML), Ph+ acute lymphoblastic leukemia (ALL), platelet-derived growth factor receptor (PDGFR) aberrancy-related myelodysplastic or myeloproliferative pathologies, kit+ expressing advanced gastrointestinal stromal tumors (GIST), and for FIP1L1-PDGFRα gene fusion expressing hypereosinophilic syndrome (HES) or chronic eosinophilic leukemia (CEL).1 Imatinib is available in 100 mg and 400 mg tablets for case-dependent single agent or adjunct therapy1. Therapeutic doses range from 100 mg to 800 mg/day, depending on diagnosis, age, and hepatic function.1 The drug exhibits pH-dependent solubility in aqueous solutions (soluble at pH ≤ 5.5), varying solubility in polar protic solvents, and is immiscible in polar aprotic liquids.1

A co-expression study was undertaken to evaluate the correlated expression of MDM2 and VEGF, finding that, over eight different cancer cell lines, higher MDM2 expression meant higher VEGF mRNA, with the cell lines with lost
