The present invention relates to chalcone and chalcone derivatives and analogs which are useful as angiogenesis inhibitors. The present compounds, which are inexpensive to synthesize, exhibit unexpectedly good activity as angiogenesis inhibitors. The present invention also relates to the use of chalcone and its analogs as antitumor/anticancer agents and to treat a number of conditions or disease states in which angiogenesis is a factor, including angiongenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.

We report here on a one-pot stereoselective synthesis of strained sulfonyl benzonorcaradienes, which proceeds through base-mediated tandem annulation of o-bis-sulfonylmethyl arenes with diversified chalcones (α,β-unsaturated carbonyls) via intermolecular desulfonylative cyclopropanation, followed by intramolecular condensation. A plausible mechanism is proposed and discussed. The proposed synthetic
A series of 1,3,5-triaryl-2-pyrazolines 2a-g were synthesized by the reaction of 4,4'-disubstituted chalcone with phenyl hydrazine. All these compounds were characterized by NMR, IR and mass spectral and single crystal XRD data. All the synthesized products were screened for their in vitro antimicrobial, analgesic and antioxidant properties. The docking studies were carried out for these compounds against the active site of methionyl-tRNA synthetase (metRS). Some of the tested compounds exhibited significant antimicrobial, analgesic, DPPH scavenging activities and molecular binding.
