Oxathiapiprolin is the first member of a new class of piperidinyl thiazole isoxazoline fungicides with exceptional activity against plant diseases caused by oomycete pathogens. It acts via inhibition of a novel fungal target-an oxysterol binding protein-resulting in excellent preventative, curative and residual efficacy against key diseases of grapes, potatoes and vegetables. Oxathiapiprolin is being developed globally as DuPont™ Zorvec™ disease control with first registration and sales anticipated in 2015.

The review points out the importance of a variety of parameters for successful treatment of immunologically mediated lung diseases by inhalation of drug containing aerosols with particular references to physico-chemical properties of formulations, aerosol parameters, pharmacokinetics, and lung deposition in experimental animals and humans. The prospects for the use of these types of formulations for clinical treatment of asthma, lung transplant rejection processes and other lung diseases are summarized.

The review points out a key role of delivery systems in increasing the therapeutic effectiveness of cyclosporine. Comparative studies of the prior marketed formulation, Sandimmune, with a new microemulsion formulation, Neoral, are discussed including some data on clinical development of Neoral.

A new biospecific method for one-stage isolation of collagen peptides containing fibronectin-binding sites is proposed. The alpha 1 CB7-peptide of type-I collagen cyanogen bromide cleavage was isolated by means of affinity chromatography on adsorbents containing an immobilized gelatin-binding domain (45,000 relative molecular mass) of fibronectin.
View Article and Find Full Text PDFA new method for the preparative isolation of anionic phospholipids with the use of chromatography on adsorbents containing primary amino groups has been developed. The method combines elements of bioaffinity and ion-exchange chromatography. Synthesis of adsorbents based on Spheron and silica supports with immobilized neomycin, L-lysine, or aminoalkyl groups was carried out.
