Synthesis and anti-inflammatory activity of aromatic glucosinolates
摘要:
Aromatic GLs are important members of the glucosinolate family of compounds because of their potential biological activity and medicinal properties. This study has shown success in the high yielding synthesis of some important aromatic GLs as well as the results of testing for anti-inflammatory properties of the synthetic GLs. 3,4-Dimethoxyphenylglucosinolate was found to be the most active anti-inflammatory of the seven glucosinolates assayed.

α-glucosinolates are also promising compounds for medicinal applications and hence have to be produced synthetically for any bio-activity studies. Here we report on the successful synthesis of a series of α-glucosinolates: α-neoglucobrassicin, α-4-methoxyglucobrassicin, 2,3-dichlorophenyl-α-glucosinolate for the first time. Testing for anti-inflammatory properties of these synthetic GLs, however, did not yield
Discovery of Natural Product‐Based Fungicides (II): Semisynthesis and Biological Activity of Sarisan Attached 3‐Phenylisoxazolines as Antifungal Agents
the discovery and development of naturalproducts‐basedfungicides, a series of thirty‐one sarisan attached 3‐phenylisoxazolines were synthesized and evaluated for their antifungalactivities against five phytopathogenic fungi (B. cinerea, C. lagenarium, A. solani, F. solani, and F. graminearum). Among all title sarisan derivatives, compounds IV2, IV14 and IV23 showed potent antifungalactivity against
azomethine imines with in situ generated nitrile oxides has been developed. This is the first example of employing a reaction partner containing two heteroatoms in the [3+3] cycloaddition involving azomethine imines. This strategy not only provides structurally diverse N,O-heterocycles but also greatly enriches the chemistry of azomethine imines and nitrile oxides.

4]oxadiazolo[4,5-c]pyrimidine-5,7(6H)-dione derivatives was developed through a [3 + 2] cycloaddition of uracil derivatives and nitrileoxides. In the one step reaction, CN and CO bonds were constructed, the target compounds were efficiently obtained in good yields. The method represents a valuable way to obtain highlyfunctional fused bicyclic heterocycle derivatives in a simple, rapid and practical manner

A novel class of 5H-[1,2,4]oxadiazolo[4,5-a]pyrimidine derivatives was prepared, characterized, and tested for its antibacterial and anticancer potential against thirteen strains and five human cancer cell lines. The synthetic method was optimized, and a proposed reaction mechanism was also presented. The compounds containing the 5-bromo-pyrimidine moiety exhibited moderate antibacterial potencies
