The synthesis and biologicalevaluation of a new class of histamine H2 antagonists with N-cyano-N'-[omega-[3-(1-piperidinylmethyl)phenoxy] alkyl]guanidine partial structure are described as part of an extensive research program to find model compounds for the development of new radioligands with high H2 affinity and specific activity. High receptor affinity is achieved by an additional (substituted)
A series of novel 2-((1-substituted-1H-1,2,3-triazol-4-yl/3-substitutedisoxazol-5-yl)methoxy) substituted pyridine,
1-((1-substituted-1H-1,2,3-triazol-4-yl/3-substitutedisoxazol-5-yl)methyl)substituted pyridin-2(1H)-one was prepared
from 2-oxo-6-phenyl/methyl-4-(trifluoromethyl)-1,2-dihydropyridine-3-carbonitrile 3 via propargylation followed by 1,3-
dipolar cycloaddition of the propargyl derivatives 4 and 5. These triazole/isoxazole tagged pyridine derivatives were
evaluated for antitumor activity against breast cancer cell lines such as MDA-MB-231, MCF-7 etc. The results indicated
that compounds 6e, 6f, 8e and 8f were found to be active on MDA-MB-231, while 6h and 8h were active on MCF-7.

A new amide synthesis strategy based on a fundamental mechanistic revision of the reaction of thioacids and organic azides is presented. The data demonstrate that amines are not formed as intermediates in this reaction. Alternative mechanisms proceeding through a thiatriazoline intermediate are suggested. The reaction has been applied to the preparation of simple and architecturally complex amides

The present invention relates to substrates comprising covalently attached antimicrobial polymers, which act as synthetic mimics of antimicrobial peptides (SMAMPs) and are preferably obtained by ring opening metathesis polymerization (ROMP). The inventive antimicrobial polymers exhibit a molecular weight of more than 100,000 g mol
−1
and are preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. Covalent bonding may be carried out using a photoreactive crosslinker but also by “grafting onto” or “grafting from”. The present invention is also directed to uses of the inventive antimicrobial polymers as defined herein, e.g. for antimicrobially coating a surface of such a substrate with a layer of the inventive antimicrobial polymer.
