Sunlight powered degradation of pentoxifylline CsLiFeO as a green reusable photocatalyst: Mechanism, kinetics and toxicity studies.

The degradation of Pentoxifylline (PXF) was achieved successfully by green energy in a built-in solar photocatalytic system using hybrid LiCs ferrites (LiCsFeO) as magnetically recoverable photocatalysts. Kinetics showed a first-order reaction rate with maximum PXF removal of 94.91% at mildly acidic pH; additionally, the ferromagnetic properties of catalyst allowed recovery and reuse multiple times, reducing costs and time in degradation processes.

Insulin Therapy for Diabetes Epidemic: A Patent Review.

Diabetes is a serious and chronic problem that can be attributed to the insufficient release of the insulin or when body does not respond to the insulin which is already present. This disease has been targeted for corrective action and implementation among four non-communicable diseases by world leaders according to WHO report. The prevalence of diabetes has been estimated to be double from 4.

Molecular modeling studies on G-quadruplex complexes of telomerase inhibitors: structure-activity relationships.

Inhibition of the ability of the enzyme telomerase to add telomeric repeats to the end of chromosomes is a novel target for potential anticancer therapy. This paper examines the hypothesis that compounds possessing a planar aromatic chromophore inhibit telomerase via stabilization of, and binding to, a folded guanine quadruplex structure. Two series of telomerase inhibitors have been designed based on the 2,6-disubstituted amidoanthracene-9,10-dione and 3,6-disubstituted acridine chromophores in order to investigate structure-activity relationships between biological activity and substituent group size.

Human telomerase inhibition by regioisomeric disubstituted amidoanthracene-9,10-diones.

Telomerase is an attractive target for the design of new anticancer drugs. We have previously described a series of 1,4- and 2, 6-difunctionalized amidoanthracene-9,10-diones that inhibit human telomerase via stabilization of telomeric G-quadruplex structures. The present study details the preparation of three further, distinct series of regioisomeric difunctionalized amidoanthracene-9,10-diones substituted at the 1,5-, 1,8-, and 2,7-positions, respectively.

Thermodynamic, kinetic, and conformational properties of a parallel intermolecular DNA triplex containing 5' and 3' junctions.

The interaction of the 11-mer oligodeoxypyrimidine d(TCTTCTUTCCT) with the 17 bp duplex d(CGCTAGAAGAAAGGACG).d(CGTCCUTTCTTCTAGCG) in forming an intermolecular DNA triplex has been examined in solution by surface plasmon resonance (SPR), UV thermal denaturation, circular dichroism (CD), and NMR methods. Thermodynamic data were also acquired for the shorter 15 bp target duplex d(CGCTAGAAGAAAGGA).
