moiety, the optimal activity was reached with either an allyl or a 1-butenyl group in conjugation with the benzene ring. The compounds 5 and 19 exerted better neuroprotective effects against epilepsy in vitro (cell) and in vivo (mouse) models. This study provides valuable data for further exploration and application of these compounds as potential anti-seizure medicines.

O and p=0-1; and G denotes low-molecular-weight organic or mineral acid, sodium, potassium or ammonium cations, or water. Said derivatives have antiaggregant, anticoagulant and vasodilatory properties. The invention further relates to a method for producing said derivatives by reacting N-substituted piperazines either with carboxamide amidating agents or salts thereof, or with haloalkyl sulfonic acids or salts thereof in organic solvents or in water in the presence of bases. The compounds may be used for the prophylaxis and treatment of disorders of the hemostatic system.
trifluoroacetic acid (TFA) was applied to the binding site analysis of ester linkages between lignin and glucuronoxylan in Fagus crenata wood. Based on the conjugate acid DDQ-oxidation of a watersoluble lignin-carbohydratecomplex (LCC-WE) from the beech wood, the frequency of the ester bonds between the lignin and glucuronic acid residue of glucuronoxylan was determined to be 1.6 per molecule of LCC-WE

identified a class of triarylpyrazole compounds that inhibit TLR signaling by modulation of the protein–protein interactions essential to the pathway. We have now systematically examined the structural features essential for inhibition of this pathway, revealing characteristics of compounds that inhibited all TLRs tested (pan‐TLR signalinginhibitors) as well as compounds that selectively inhibited certain
