introduction: due to the interesting pharmacological properties of radiolabeled metal oxine derivatives such as cell internalization, tumor avidity and antiproteosome activity, 111in-tris[8-hydroxy-2-methylquinoline] (111in-hmq) was developed in this study. methods: 111in-hmq was prepared using 111incl3 and 8-hydroxy-2-methylquinoline (hmq) for 60 min at 100°c (radiochemical purity: >99% itlc, ...
در این کار پژوهش بیشتر سنتز ترکیبهای مختلف سه حلقه ای فنل با یک نوع هالوژن و هالوژنهای مختلف و کندن برم از آنها موردنظر است و مشتقهای مختلف از این نوع ترکیبات که در زیر شرح داده شده است سنتز گردیده است . علاوه براین از روشهای سنتزی برای تائید ساختمان ترکیبهای سه حلقه ای استفاده شده است . همچنین سنتز این ترکیبها امکان میدهد که خواص بیولوژیکی و شیمیائی آنها با ترکیبات مشابه دوحلقه ای و چهارحلقه ا...
A new series of quinoline derivatives incorporated to glycosides and biologically active heterocyclic moieties were synthesized starting with 6-bromo-4-hydroxyquinaldine (6-bromo-4-hydroxy-2-methylquinoline) compound 1. Some of the synthesized compounds were evaluated for their antibacterial and antifungal activities. Most of the tested compounds exhibited potential antibacterial activity again...
The first example of ligand-enabled C(sp(3))-alkynylation of 8-methylquinoline is reported. The reaction is catalysed by well-defined Pd(ii) complexes. The present C(sp(3))-alkynylation has a broad substrate scope as well as functional group tolerance and proceeds efficiently under mild conditions.
(R)-6-[(3-{[4-(5-{[2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethyl]amino}pent-1-yn-1-yl)phenyl] carbamoyl}phenyl)sulphonyl]-4-[(3-methoxyphenyl)amino]-8-methylquinoline-3-carboxamide trifluoroacetic acid (GS-5759) is a bifunctional ligand composed of a quinolinone-containing pharmacophore [β2-adrenoceptor agonist orthostere (β2A)] found in several β2-adrenoceptor agonists, including...
Inhaled long-acting β(2)-adrenoceptor agonists (LABA) that act as bronchodilators and the oral anti-inflammatory phosphodiesterase 4 (PDE4) inhibitor roflumilast are both approved therapies for chronic obstructive pulmonary disease (COPD). Here we describe the activity of a novel, inhaled, bifunctional, small molecule (R)-6-[(3-{[4-(5-{[2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethy...
