Integrating chemosensors for amine-containing compounds into cross-linked dendritic hosts
摘要:
Trifluoroacetylazo dye 1, a known chemosensor for amines, has been integrated into cross-linked dendrimer hosts. Thus, boronic acid 16 was linked to iododye 9 via a Suzuki coupling reaction. In situ deprotection and alkylation with dendrons 3 and 4, containing 8 homoallyl or allyl ether groups, respectively, afforded dendrons 18 and 19 with chemosensor units at their focal point. Conversion of 18 (19) to the bis-imine of butane 1,4-diamine, extensive cross-linking via the ring closing metathesis reaction with Grubbs catalyst 25, and hydrolysis produced dendrimer hosts 28 and 29. Host-guest studies with a small library of amines and alcohols showed 28 and 29 to selectively signal certain diamines but not due to template mediated imprinting. (C) 2004 Elsevier Ltd.

Cross-Linked Dendrimer Hosts Containing Reporter Groups for Amine Guests
摘要:
The integration of a chromogenic reporter group into the recently reported (Zimmerman, S. C.; Wendland, M. S.; Rakow, N. A.; Zharov, I.; Suslick, K. S. Nature 2002, 418, 399-403) monomolecular imprinting approach is described. The resulting highly cross-linked, macromolecular hosts show rapid, selective, high affinity, two-point binding of straight-chain diamine guests. Over longer times, the hosts are more promiscuous, binding a broader range of diamines. A rigorous test of imprinting was performed wherein the cross-reactivities of two dendrimers derived from different templates are compared. The test reveals a guest-dependent kinetic binding effect masquerading as evidence of a highly selective two-point imprinting process.
A series of thiazole derivatives which are substituted in the 2-position by a substituted morpholin-4-yl moiety, being selective inhibitors of P13 kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.
A series of 6,7-dihydro[1,3]thiazolo[5,4-c]pyridin-4(5H)-one derivatives, and analogues thereof, which are substituted in the 2-position by an optionally substituted morpholin-4-yl moiety, being selective inhibitors of PI3 kinase enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive or ophthalmic conditions.
