The design and synthesis of molecular probes competent for pH signaling within or beyond a certain range is a complicated matter. Herein a new mechanism for ''OFF-ON-OFF'' absorbance and fluorescence intensities vs. pH behaviour is described. The probe design is

17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) is an enzyme that catalyzes NADPH-dependent reduction of the weak estrogen, estrone, into the most potent estrogen, estradiol, which exerts proliferative effects via the estrogen receptors. Overexpression of 17β-HSD1 in estrogen-responsive tissues is related to

Ortho-hydroxylation of cinnamates is a key step in coumarin biosynthesis in plants. Ortho-hydroxylated cinnamates undergo trans/cis isomerization of the side-chain and then lactonization to form coumarins. Sweet potato [Ipomoea batatas (L.) Lam.] accumulates umbelliferone and scopoletin after biotic and abiotic

A number of 7-hydroxycoumarins have been synthesised by Pechmann cyclisation using differently substituted resorcinols employing perchloric acid as the condensing agent. All the compounds have been characterised by analytical and spectroscopic methods. The anti-inflammatory properties were tested with LPS-induced inflammation
