Novel FeII and CoII Complexes of Natural Product Tryptanthrin: Synthesis and Binding with G-Quadruplex DNA
Tryptanthrin is one of the most important members of indoloquinoline alkaloids. We obtained this alkaloid from Isatis. Two novel FeII and CoII complexes of tryptanthrin were first synthesized. Single-crystal X-ray diffraction analyses show that these complexes display distorted four-coordinated tetrahedron geometry via two heterocyclic nitrogen and oxygen atoms from tryptanthrin ligand. Binding...
متن کاملMitochondrial COII Sequences
The aim of this study is to measure human mitochondrial sequence variability in the relatively slowly evolving mitochondrial gene cytochrome oxidase subunit II (CO11 ) and to estimate when the the human common ancestral mitochondrial type existed. New CO11 gene sequences were determined for five humans (Homo sapiens), including some of the most mitochondrially divergent humans known; for two py...
متن کاملA series of tetraazalene radical-bridged M2 (M = CrIII, MnII, FeII, CoII) complexes with strong magnetic exchange coupling.
The ability of tetraazalene radical bridging ligands to mediate exceptionally strong magnetic exchange coupling across a range of transition metal complexes is demonstrated. The redox-active bridging ligand N,N',N'',N'''-tetra(2-methylphenyl)-2,5-diamino-1,4-diiminobenzoquinone (NMePhLH2) was metalated to give the series of dinuclear complexes [(TPyA)2M2(NMePhL2-)]2+ (TPyA = tris(2-pyridylmethy...
متن کاملMolar Excess Volumes and Excess Isentropic Compressibilities of Ternary Mixtures Containing 2-Pyrrolidinone
Molar excess Volumes, Vijk and speeds of sound , uijk of 2-pyrrolidinone (i) + benzene or toluene (j) + ethanol (k) ternary mixture have been measured as a function of composition at 308.15 K. The observed speeds of sound data have been utilized to determine excess isentropic compressiblities, ( E S κ )ijk of ternary (i + j + k) mixtures. Molar excess volumes, Vijk and excess isentropic compres...
متن کامل2-pyrrolidinone moiety is not critical for the cognition-enhancing activity of piracetam-like drugs.
Following the indications of previous work, 2-pyrrolidinone moiety of piracetam and piracetam-like compounds has been opened to the corresponding amide derivatives. As found previously in the case of 1,4-diazabicyclo[4.3.0]nonan-9-one compounds, the cognition-enhancing activity of 2-pyrrolidinone compounds is maintained in most cases, suggesting that this moiety is not crucial for activity.
