Twelve novel 20-sulfonylamidine derivatives (9a–9l) of camptothecin (1) were synthesized via a Cu-catalyzed three-component reaction. They showed similar or superior cytotoxicity compared with that irinotecan (3) against A-549, DU-145, KB, and multidrug-resistant (MDR) KBvin tumor cell lines. Compound 9a demonstrated better MDR cells 1 3. Mechanistically, induced significant DNA damage by selectively inhibiting Topoisomerase (Topo) I activating the ATM/Chk related damage-response pathway. In...

Three novel series of N3-substituted imidacloprid derivatives were designed and synthesized, their structures identified on the basis satisfactory analytical spectral ((1)H NMR, (13)C MS, elemental analysis, X-ray) data. Preliminary bioassays indicated that all exhibited significant insecticidal activities against Aphis craccivora, with LC50 values ranging from 0.00895 to 0.49947 mmol/L, some them comparable those control imidacloprid. Some key structural features related identified, binding...

Benzophenone hydrazone derivatives are among the most important classes of synthetic insecticides. In an effort to discover new molecules with good insecticidal/acaricidal activities, a series novel benzophenone N-acylated thiourea and urea was synthesized bioassayed.All these compounds exhibited excellent bioactivities against T. cinnabarinus B. brassicae, especially towards LC50 values ranging from 0.305 2.036 mmol L(-1). Moreover, acaricidal activities 8a-i, 12b-f 12h were 2.5-5.5-fold...

As part of our continuous efforts to discover novel c-Met inhibitors as antitumor agents, four series thiazole/thiadiazole carboxamide-derived analogues were designed, synthesised, and evaluated for the in vitro activity against human cancer cell lines. After five cycles optimisation on structure-activity relationship, compound 51am was found be most promising inhibitor both biochemical cellular assays. Moreover, exhibited potency several mutants. Mechanistically, not only induced cycle...
