Amidine group—or guanidine group—containing silane
A silane of the formula (I) containing at least one aliphatic amidine group- or guanidine group-containing alkoxy group, to a method for producing same, to conversion products thereof, and to the use thereof as a catalyst in curable compositions, in particular based on silane group-containing polymers. The silane of the formula (I) is largely odorless and non-volatile at room temperature. The silane accelerates the hydrolysis and condensation reaction of silane groups very effectively without impairing the storage stability of silane group-containing polymers. Additionally, the silane is very tolerable in silane group-containing compositions, whereby such compositions are not prone to separate, migrate, or evaporate the catalyst.
Rapid-curing, migration-free composition based on organic polymers containing silane groups
The invention relates to a composition comprising at least one organic polymer that contains silane groups and at least one catalyst of formula (I). The composition is low in emissions and low-odor, has a good shelf-life, cures rapidly to form a mechanically high-quality, durable material with a very low propensity for migration-related defects such as exudation or dirt retention by the substrate. The composition is particularly suitable for use as an adhesive, sealant or coating.

Sphingosine kinase inhibitors
Sphingosine kinases are enzymes that catalyze the biosynthesis of sphingosine-1-phosphate. The invention provides compounds that are effective for inhibition of sphingosine kinase type 1, sphingosine kinase type 2, or both. Certain compounds are selective for sphingosine kinase type 2 relative to sphingosine kinase type 1. Compounds of the invention can be used in treatment of a range of diseases wherein increasing the level of sphingosine-1-phosphate in blood is medically indicated. Diseases that can be treated by administration of an effective dose of a compound of the invention include a neoplastic disease that involves excess vascular growth; macular degeneration or diabetic retinopathy; an allergic disease such as asthma, an inflammatory disease of the eye such as uveitis, scleritis, or vitritis; an inflammatory disease of the kidney; a fibrotic disease; atherosclerosis; or pulmonary arterial hypertension. A compound of the invention can be used to improve the integrity of a vascular barrier in a disease where the vascular barrier is disrupted, such as cancer or Alzheimer's disease.
