Anodic oxidation of 1,2,3,4-tetrahydronaphthalene and isochroman analogs of 1-benzyl and 1-phenethyl isoquinoline alkaloids. Products and mechanism of the intramolecular cyclization
Structure–activity relationship of C5-curcuminoids and synthesis of their molecular probes thereof
摘要:
A series of novel analogues of 1,5-bis(4-hydroxy-3-methoxyphenyl)-penta-(1E,4E)-1,4-dien-3-one (C-5-curcumin), which is a natural analogue of curcumin isolated from the rhizomes of Curcuma domestica Val. (Zingiberacea), were synthesized and evaluated for their cytotoxicities against human colon cancer cell line HCT-116 to conclude the SAR of C-5-curcuminoids for further development of their use in cancer chemotherapy: (1) Bis(arylmethylidene) acetone serves as a promising skeleton for eliciting cytotoxicity. (2) The 3-oxo-1,4-pentadiene structure is essential for eliciting cytotoxicity. (3) As for the extent of the aromatic substituents, hexasubstituted compounds exhibit strong activities, in which 3,4,5-hexasubstitution results in the highest potency. (5) The symmetry between two aryl rings is not an essential requirement for bis(arylmethylidene) acetones to elicit cytotoxicity. (6) para-Positions allows the installation of additional functional groups for use as molecular probes. By taking advantage of the SAR diagram, we have elaborated several advanced derivatives having GI(50) of single-digit micromolar potencies that will function as molecular probes to target and/or report key biomolecules interacting with curcumin and C-5-curcumin.

We evaluated the antimicrobialactivity of 25 monoketonecurcuminoids (MKCs) against a representative panel of cariogenicbacteria in terms of their minimum inhibitory concentration (MIC) values. Curcumin A (10) displayed promising activityagainst Streptococcus mutans (MIC = 50 μg/ml) and Streptococcus mitis (MIC = 50 μg/ml) as well as moderate activityagainst S. sanguinis (MIC = 100 μg/ml), Lactobacillus
