Cleaving DNA with DNA.
A DNA structure is described that can cleave single-stranded DNA oligonucleotides in the presence of ionic copper. This "deoxyribozyme" can self-cleave or can operate as a bimolecular complex that simultaneously makes use of duplex and triplex interactions to bind and cleave separate DNA substrates. Bimolecular deoxyribozyme-mediated strand scission proceeds with a kobs of 0.2 min-1, whereas th...
متن کاملIntermediate human adenovirus type 22/H10,19,37 as a new etiological agent of conjunctivitis.
Eight strains of a new intermediate adenovirus were isolated in the course of an investigation of conjunctivitis in Hiroshima City, Japan. The strain was first isolated in July 1986. All eight strains were isolated from conjunctival swab samples from patients with conjunctivitis, mainly epidemic keratoconjunctivitis. The virus was typed as adenovirus type 22 in neutralization tests and was rela...
متن کاملEvaluation of a new bombesin analogue labeled with 99mTc as potential targeted tumor scintigraphic agent
Background: Bombesin shows high affinity for Gastrin-releasing peptide (GRP) receptors which over expressed on the cell surfaces of several human tumors particularly in prostate and breast cancers. The aim of this study was labeling of designed analogue with99mTc via HYNIC and Tricine /EDDA and evaluation as potential targeted tumor scintigraphic agent. Materials and Methods: HYNIC-Bombesin wa...
متن کاملMetapyrocatachase: a new catechol-cleaving enzyme.
The enzyme, pyrocatechase, isolated and partially purified from anthranilate-adapted cells of a pseudomonad, was shown to catalyze the oxidative cleavage of the aromatic ring of catechol to cis, cis-muconic acid (1). Subsequently, through the use of 0218 and HsO~~, the two oxygen atoms incorporated across the double bond between the two hydroxyl groups were shown to be derived from atmospheric ...
متن کاملEffects of Vitamin K3 on Cytotoxicity and DNA-binding Properties of a Palladium(II) Complex as a Potential Antitumor Agent
In many diseases such as cancer, simultaneous use of two or more pharmacologically active agents will be more effective and have fewer side effects. In this study a new palladium(II) complex with formula of [Pd(phen)(py-dtc)]NO3 (where is phen 1,10-phenanthroline and py-dtc is n-propyldithiocarbamate), was synthesized. The cytotoxic activity of this complex was tested against leukemia K562 cell...
