Keskin, Fatma Ela published the artcileThe Role of Different Molecular Markers in Papillary Thyroid Cancer Patients with Acromegaly, Application of 4-(5-(4-Methoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonamide, the publication is Experimental and Clinical Endocrinology & Diabetes (2019), 127(7), 437-444, database is CAplus and MEDLINE.

Prevalence of papillary thyroid cancer (PTC) is increased in patients with acromegaly. We aimed to determine the protein expression of BRAF, RAS, RET, insulin like growth factor 1(IGF1), Galectine 3, CD56 in patients with PTC related acromegaly and to compare the extensity of these expressions with normal PTC patients and benign thyroid nodules. We studied 313 patients with acromegaly followed in Cerrahpasa Medical Faculty, Endocrinol. and Metabolism Clinic between 1998 and 2015. On the basis of availability of pathol. specimen of thyroid tissues, thyroid samples of 13 patients from 19 with acromegaly related PTC (APTC), 20 normal PTC and 20 patients with multinodulary goiter (MNG) were histopathol. evaluated. Protein expressions were determined via immunohistochem. staining in ex-vivo tumor samples and benign nodules. The incidence of PTC in acromegaly patients were 6% (n = 19). Among patients with PTC, APTC and MNG, all the immunohistochem. protein expressions we have studied were higher in papillary thyroid cancer groups (p<0.01, for all). Between PTC group without acromegaly and APTC, galectin 3 and IGF1 expression was significantly higher in acromegalic patients (p<0.01 for all) while RAS was predominantly higher in PTC patients without acromegaly (p<0.01). BRAF expression was not higher in PTC with acromegaly patients compared to PTC patients without acromegaly. Galectine 3 and IGF1 were expressed more intensively in APTC. These pos. protein expressions may have more influence on determining malign nodules among acromegaly patients.

We have designed and synthesized analogs of compound C, [4-(2-piperidinyl-1-ylethoxy)phenyl]-3-(4-pyridinyl)pyrazolo[1,5-a]pyrimidine, a non-specific inhibitor of 5′-AMP-activated protein kinase (AMPK), using a computational fragment-based drug design (FBDD) approach. Synthesizing only twenty-seven analogs yielded a compound that was equipotent to compound C in the inhibition of the human AMPK (hAMPK) α2 subunit in the heterotrimeric complex in vitro, exhibited significantly improved selectivity against a subset of relevant kinases, and demonstrated enhanced cellular inhibition of AMPK.

As a part of our continuous structure-activity relationship (SAR) studies on 1-(quinazolin-4-yl)-1-(4-methoxyphenyl)ethan-1-ols, the synthesis of derivatives and their cytotoxicity against the human lung cancer cell line A549 were explored. This led to the discovery of 1-(2-(furan-3-yl)quinazolin-4-yl)-1-(4-methoxyphenyl)ethan-1-ol (PVHD303) with potent antiproliferative activity. PVHD303 disturbed microtubule formation at the centrosomes and inhibited the growth of tumors dose-dependently in the HCT116 human colon cancer xenograft model in vivo.

Katane, Masumi published the artcileIdentification of Novel d-Amino Acid Oxidase Inhibitors by in Silico Screening and Their Functional Characterization in Vitro, Category: pyrazoles-derivatives, the publication is Journal of Medicinal Chemistry (2013), 56(5), 1894-1907, database is CAplus and MEDLINE.

D-Amino acid oxidase (DAO) is a degradative enzyme that is stereospecific for d-amino acids, including d-serine and d-alanine, which are potential coagonists of the N-methyl-d-aspartate (NMDA) receptor. Dysfunction of NMDA receptor-mediated neurotransmission has been implicated in the onset of various mental disorders such as schizophrenia. Hence, a DAO inhibitor that augments the brain levels of d-serine and/or d-alanine and thereby activates NMDA receptor function is expected to be an antipsychotic drug, for instance, in the treatment of schizophrenia. In the search for potent DAO inhibitor(s), a large number of compounds were screened in silico, and several compounds were estimated as candidates. These compounds were then characterized and evaluated as novel DAO inhibitors in vitro. The results reported in this study indicate that some of these compounds are possible lead compounds for the development of a clin. useful DAO inhibitor and have the potential to serve as active site probes to elucidate the structure-function relationships of DAO.

Davoren, Jennifer E. published the artcileDesign and optimization of selective azaindole amide M₁ positive allosteric modulators, Application In Synthesis of 19959-71-8, the publication is Bioorganic & Medicinal Chemistry Letters (2016), 26(2), 650-655, database is CAplus and MEDLINE.

Selective activation of the M₁ receptor via a pos. allosteric modulator (PAM) is a new approach for the treatment of the cognitive impairments associated with schizophrenia and Alzheimer’s disease. A novel series of azaindole amides and their key pharmacophore elements are described. The nitrogen of the azaindole core is a key design element as it forms an intramol. hydrogen bond with the amide N-H thus reinforcing the bioactive conformation predicted by published SAR and the authors’ homol. model. Representative compound 25 is a potent and selective M₁ PAM that has well aligned physicochem. properties, adequate brain penetration and pharmacokinetic (PK) properties, and is active in vivo. These favorable properties indicate that this series possesses suitable qualities for further development and studies.

Deng, Xianming published the artcileExpanding the Diversity of Allosteric Bcr-Abl Inhibitors, Category: pyrazoles-derivatives, the publication is Journal of Medicinal Chemistry (2010), 53(19), 6934-6946, database is CAplus and MEDLINE.

Inhibition of Bcr-Abl kinase activity by imatinib for the treatment of chronic myeloid leukemia (CML) currently serves as the paradigm for targeting dominant oncogenes with small mols. The discovery of GNF-2 (I, R = H) and GNF-5 (I, R = CH₂CH₂OH) was recently reported as selective non-ATP competitive inhibitors of cellular Bcr-Abl kinase activity that target the myristate binding site. Herein is used cell-based structure-activity relationships to guide the optimization and diversification of ligands that are capable of binding to the myristate binding site and rationalize the findings based upon an Abl-compound I (R = H) cocrystal. The structure-activity relationships required to obtain potent antiproliferative activity against Bcr-Abl transformed cells is elucidated, and the discovery of new compounds II (R¹ = 4-(NH₂SO₂)C₆H₄, 4-(MeSO₂NH)C₆H₄, 4-pyrazolyl), III, and IV that display improved potency or pharmacol. properties is reported. This work demonstrates that a variety of structures can effectively target the Bcr-Abl myristate binding site and provides new leads for developing drugs that can target this binding site.

Some acylhydroxypyrazole acylhydrazones, e.g., I (R = pentyl, Pr), and their 3d transition metal(II) complexes were synthesized. The ligands and their 3d transition metal complexes were characterized by elemental anal., molar conductance, magnetic susceptibility measurements and spectroscopic methods. The ligands behaved as mono-anion ONO or ONS donor mols. Microanal., electronic spectral and magnetic measurements showed the metal complexes as ML₂ type. All the synthesized compounds were screened for their in vitro antimicrobial activity against some gram pos. and gram neg. clin. bacterial strains. Antimicrobial activity test results showed that the metallic derivatives are more active against the bacterial strains than the imines.
