Abstract

In order to exploit the 430-cavity in the active sitesof neuraminidases,22 zanamivir analogs with C-1 and C-4 modification were synthesized,and their inhibitory activities against both group-1 (H5N1, H1N1)and group-2 neuraminidases (H3N2) were determined. Compound 9fexerts the most potency, with IC50value of0.013, 0.001, and 0.09 μM against H3N2, H5N1, and H1N1, whichis similar to that of zanamivir (H3N2 IC50= 0.0014 μM,H5N1 IC50= 0.012 μM, H1N1 IC50= 0.001μM). Pharmacokinetic studies of compound 9finrats showed a much longer plasma half-life (t1/2) than that of zanamivir following administration (po dose).Molecular modeling provided information about the binding model betweenthe new inhibitors and neuraminidase, with the elongated groups atthe C-1-position being projected toward the 430-loop region. Thisstudy may represent a novel starting point for the future developmentof improved antiflu agents. [ABSTRACT FROM AUTHOR]

35. GoldICatalyzed OnePot Tandem CouplingCyclization: An Efficient Synthesis of PyrroloPyrido2,1bbenzod1,3oxazin 1ones

Author

Zhou, Yu, Zhai, Yun, Ji, Xun, Liu, Guannan, Feng, Enguang, Ye, Deju, Zhao, Linxiang, Jiang, Hualiang, and Liu, Hong

Abstract

A highly efficient method has been developed for the onepot synthesis of multiring heterocyclic compounds such as pyrrolopyrido2,1bbenzod1,3oxazin1ones from oaminobenzyl alcohols viaa goldIcatalyzed tandem couplingcyclization reaction. Significantly, the strategy presents a straightforward and efficient approach to construct novel tricyclic or polycyclic molecular architectures in which two new CN bonds and one CO bond are formed in a onepot reaction operation from two simple starting materials. Moreover, a broad spectrum of substrates can participate in the process effectively to produce the desired products in good yields.

37. Metal-free synthesis of 2-substituted (N, O, C) benzothiazoles via an intramolecular C-S bond formation.

Abstract

An efficient, economical, and convenient method was developed for the preparation of 2-substituted (N, O, C) benzothiazoles from N'-substituted-N-(2-halophenyl)thioureas, O'-substituted-N-(2-halophenyl) carbamothioates, or N-(2-halophenyl) thioamides via a base-promoted cyclization in dioxane without any transition metal. A one-pot variant combining the synthesis of the thiourea and the cyclization was also demonstrated. High yields were obtained, and a variety of functional groups were tolerated under these conditions. Transition-metal-free, mild reactive conditions, wide application scope, and shorter reaction times make this method superior to the reported methods for the synthesis of 2-substituted benzothiazoles and suitable for combinatorial format.

Abstract

A novel and efficient process for the synthesis of alpha-sialyl spirohydantoin analogues via one-pot sequential reaction involving various carbodiimides and peracetylated Neu5Ac is reported. BF(3) x Et(2)O mediating intramolecular N-sialylation with excellent alpha-selectivity is first demonstrated.
