• Synthetic studies towards the mulberry Diels–Alder adducts: H-bond accelerated cycloadditions of chalcones
  作者：Sompong Boonsri、Christian Gunawan、Elizabeth H. Krenske、Mark A. Rizzacasa

  The methyl ether derivatives 2, 4 and 6 of the mulberry Diels–Alder adducts chalcomoracin (1) and mulberrofuran C (3) and kuwanon J (5) respectively have been synthesized by a thermal [4 + 2]-cycloaddition reaction between a chalcone and dehydroprenyl diene. A H-bonded ortho OH substituent on the chalcone was found to be essential for Diels–Alder reactivity. Density functional theory calculations show that the OH group lowers the barrier for the Diels–Alder reaction by 2–3 kcal mol−1 compared with OMe. The acceleration by the OH group is traced to two transition-state effects: a stronger diene–chalcone interaction and better planarity of the aryl–diene unit.

  Chalcones have been identified as interesting compounds with cytotoxicity, anti-inflammatory and antioxidant properties. In the present study, simple methoxychalcones were synthesized by Claisen-Schmidt condensation reaction and evaluated for above biological activities. The structures of the compounds were established by IR, (1)H NMR and mass spectral analysis. The data revealed that compound 3s (99-100% at 10 mu M concentration) completely inhibit the selected five human cancer cell lines as compared to standard flavopiridol and gemcitabine (70-90% at 700 nM and 500 nM concentrations, respectively), followed by 3a, 3n, 3o, 3p, 3q, 3r. Among the tested compounds 3l, 3m, 3r, and 3s exhibited promising anti-inflammatory activity against TNF-alpha and IL-6 with 90-100% inhibition at 10 mu M concentration. DPPH free radical scavenging activity was given by the compounds 3o, 3n, 3l, 3r, 3m, 3a, 3p, 3c and 3s at 1 mM concentration. Overall, 3s was obtained as lead compound with promising anticancer, anti-inflammatory and antioxidant activities. Bioavailability of compounds were checked by in vitro cytotoxicity study and confirmed to be nontoxic. The structure activity relationship (SAR) and in silico drug relevant properties (HBDs, HBAs, PSA, c Log P, ionization potential, molecular weight, E(HOMO) and E(LUMO)) further confirmed that the compounds were potential candidates for future drug discovery study.

• The synthesis of 4,6-diaryl-2-pyridones and their bioactivation in CYP1 expressing breast cancer cells

  As part of a programme to develop anticancer prodrugs which are activated by cytochrome P450 (CYP) 1B1, a library of 4,6-diaryl-2-pyridones was synthesised in yields of 6-60% from the corresponding chalcones. A number of these derivatives showed promising antiproliferative activities in human breast cancer cell lines which express CYP1B1 and CYP1A1, while showing little toxicity towards a non-tumour breast cell line with no CYP expression. Metabolism studies provided evidence supporting the involvement of CYP1 enzymes in the bioactivation of these compounds.
• Investigation of Chalcones as Selective Inhibitors of the Breast Cancer Resistance Protein: Critical Role of Methoxylation in both Inhibition Potency and Cytotoxicity

  ABCG2 plays a major role in anticancer-drug efflux and related tumor multidrug resistance. Potent and selective ABCG2 inhibitors with low cytotoxicity were investigated among a series of 44 chalcones and analogues (1,3-diarylpropenones), by evaluating their inhibitory effect on the transport of mitoxantrone, a known ABCG2 substrate. Six compounds producing complete inhibition with IC50 values below 0.5 mu M and high selectivity for ABCG2 were identified. The number and position of methoxy substituents appeared to be critical for both inhibition and cytotoxicity. The best compounds, with potent inhibition and low toxicity, contained an N-methyl-1-indolyl (compound 38) or a 6'-hydroxyl-2',4'-dimethoxy-1-phenyl (compound 27) moiety (A-ring) and two methoxy groups at positions 2 and 6 of the 3-phenyl moiety (B-ring). Methoxy substitution contributed to inhibition at positions 3 and 5, but had a negative effect at position 4. Finally, methoxy groups at positions 3, 4, and 5 of the B-ring markedly increased cytotoxicity and, therefore, should be avoided.
