“…2-Aminopyridines serve as useful chelating ligands in a variety of inorganic and organometallic applications [12] and also act as monodentate ligands that coordinate metal ions through the aromatic nitrogen in most cases [12][13][14]. In addition, there are several reports on 2aminopyridine complexes in which the amino group also participates in coordination [4,[15][16][17].…”

A novel Cu(II) complex 1 of 2-methoxy-5-sulfamoylbenzoic acid (Hsba) and eight novel mixed-ligand Cu(II) complexes 2–9 have been prepared using Hsba and 2-aminopyridine derivatives [2,3-diaminopyridine (2,3dap), 2,3-diamino-5-bromopyridine (2,3da5Brp), 2,3-diamino-5-chloropyridine (2,3da5Clp), 2-amino-3-benzyloxypyridine (2a3bxp), 2-amino-3-hydroxypyridine (2a3OHp), 2-amino-3-methylpiridine (2a3mp), 2-amino-3-methyl-6-ethylpiridine (2a3m6Etp) and 2-amino-3-nitro-6-methylpiridine (2a3NO26mp)], respectively. The structures of the amorphous metal complexes have been proposed by evaluating the data obtained from elemental analysis, inductively coupled plasma optical emission spectrometry (ICP-OES), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), magnetic susceptibility and molar conductivity methods.

Bu çalışmada, ilk olarak 3-aminobenzensülfonilamit (abs) ile maleik anhidritin (mal) tepkimesinden (E)-4-okso-4-(3sülfamoyilfenil)amino)büt-2-enoik asit (Hmabsmal) bileşiği sentezlenmiştir. Daha sonra Hmabsmal bileşiği ile 2aminopiridinin (ap) proton transfer tuzu (1) hazırlanmıştır. Bu maddelerin değişik yöntemlerle Co(II) (2) ve Cu(II) (3 ve 4) geçiş metal kompleksleri sentezlenmiştir. Proton transfer tuzunun yapısı elementel analiz, 1 H-NMR, 13 C-NMR, FT-IR, UV-Vis metotları ile aydınlatılmıştır. Amorf halde elde edilen geçiş metal komplekslerinin yapıları ise elementel analiz, ICP-OES, FT-IR, UV-Vis, termal analiz, manyetik duyarlılık ve molar iletkenlik sonuçları dikkate alınarak önerilmiştir. Ayrıca, sentezlenen maddelerin insan eritrosit hCA I ve hCA II izoenzimleri üzerindeki inhibisyon etkilerini belirlemek üzere in vitro çalışmalar yapılmıştır. Yeni sentezlenen maddelerin izoenzimlerin esteraz aktivitesini inhibe ettiği, hidrataz aktivitesini ise sadece 3 bileşiğinin inhibe ettiği tespit edilmiştir. Bu maddelerin inhibisyon değerlerinin kontrol bileşiği asetazolamid (AAZ) değerleri ile kıyaslanabilir büyüklükte olduğu tespit edilmiştir.

Two novel proton transfer compounds (HAP) + (SAMAL) -and (HBI) + (SAMAL) -.H 2 O were obtained from (E)-4-oxo-4-(4-sulfamoylphenylamino)but-2-enoic acid (HSAMAL) and 2-aminopyridine (AP) or 1H-benzimidazole (BI), respectively. Copper(II) complexes of salts and of HSAMAL have also been prepared. They have been characterized by elemental, spectral, thermal analyses, magnetic measurement and molar conductivity. Human carbonic anhydrase isozymes (hCA I and hCA II) were purified from erythrocytes by using affinity chromatography as 84.40 and 188.71 fold, respectively. The inhibitory effects of synthesized compounds and acetazolamide (AAZ, control compound) on the hydratase and esterase activities of hCA isozymes have been studied as in vitro to find out their antiglaucoma potentials. The inhibition constant (K i ) values of the compounds were in the range of 0.18 ± 0.007 to 10.24 ± 0.014 µmol L -1 for hCA I, and 0.12 ± 0.004 to 130.11 ± 0.021 µmol L -1 for hCA II.
