Optical imaging in the shortwave infrared region (SWIR, 1000?2000 nm) provides high-resolution images in complex systems. Here we explore substituent placement on dimethylamino flavylium polymethine dyes, a class of SWIR fluorophores. We find that the pos

The present disclosure provides NIR- and SWIR-active small molecule polymethine dyes with improved properties for use in optical imaging, photothermal therapy, and photodynamic therapy.
Ethynylflavones, highly potent, and selective inhibitors of cytochrome P450 1A1
Goyal, Navneet,Liu, Jiawang,Lovings, Lanese,Dupart, Patrick,Taylor, Shannon,Bellow, Sydni,Mensah, Lydia,McClain, Erika,Dotson, Brandan,Sridhar, Jayalakshmi,Zhang, Xiaoyi,Zhao, Ming,Foroozesh, Maryam

The flavone backbone is a well-known pharmacophore present in a number of substrates and inhibitors of various P450 enzymes. In order to find highly potent and novel P450 family I enzyme inhibitors, an acetylene group was incorporated into six different p
Regioselective synthesis of flavone derivatives via DMAP-catalyzed cyclization of o-alkynoylphenols

A catalytic amount of DMAP promoted cyclization of o-alkynoylphenols via a 6-endo cyclization mode leading to flavone derivatives in high yields without forming 5-exo cyclized aurone derivatives. Utilizing this method, methoxy substituted flavone and alkyl substituted γ-benzopyranone derivatives were synthesized.
Efficient synthesis of biflavones having a ring-A ring of two flavone units using Suzuki cross-coupling reactions
Kohari, Yoshihito,Hoshino, Yukio,Matsuyama, Haruo,Nakano, Hiroto
scheme or table, p. 1871 - 1879 (2011/03/22)
Biflavones having a A ring-A ring of two flavone units were easily prepared by using Suzuki cross-coupling reaction of borylated flavones with bromoflavones or flavone-5-triflate in good to excellent yields. The Japan Institute of Heterocyclic Chemistry.
Microwave enhanced palladium catalysed coupling reactions: A diversity-oriented synthesis approach to functionalised flavones
Fitzmaurice, Richard J.,Etheridge, Zac C.,Jumel, Emelie,Woolfson, Derek N.,Caddick, Stephen
, p. 4814 - 4816 (2007/10/03)
Microwave enhanced diversity-oriented synthesis (MEDOS) using palladium catalysed protocols is introduced as a powerful new strategy for the synthesis of systematically modified small molecules and is highlighted by application to functionalised flavones. The Royal Society of Chemistry 2006.
