The present disclosure relates to compounds of Formula I, II, or III and compositions of the same, which are reversible off-on or ratiometric fluorescent iron sensors and are useful in live-cell imaging of labile iron ions and their quantification in subcellular compartments, as well as treatment of diseases associated with iron dyshomoestasis.

Fluorescent probes

This invention is in the field of fluorescence imaging and relates to a new near infrared (NIR) reactive oxygen species (ROS) sensor designed with controlled fluorescence on-off switching mechanism.

Turn-on near infrared fluorescent probes for imaging lysosomal ROS in live cells at subcellular resolution

The present disclosure relates to compositions and methods for providing full spectrum photo protection to skin, which includes protection from infrared (IR) radiation and/or visible light in addition to protection from UV radiation. The compositions typically include: (a) silymarin; (b) one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, polydatin, and hesperetin; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier. The compositions are unique in that the combination of (a), (b), optional (c), and (d) alone, provide at least full spectrum protection from ultraviolet radiation (UV), visible light, and infrared radiation (IR). The composition can additionally, optionally, include one or more UV filters to further enhance protection from UV radiation.

Cosmetic compositions and methods for providing full spectrum photo protection

The present disclosure relates to methods and compositions for providing at least broad spectrum photo protection to skin, which includes protection from at least infrared (IR) radiation and/or visible light. The methods typically entail applying to skin a cosmetic composition comprising: (a) one or more antioxidants selected from the group consisting of baicalin, Venuceane&#x2122;, ferulic acid, polydatin, silymarin, punica granatum extract, mango leaf extract, soliprin, catechin, hesperetin, astilbin, and DHC V; (b) optionally, one or more solubilizers; and (c) a cosmetically acceptable carrier; wherein the combination of (a), optional (b), and (c) alone, provide at least broad spectrum protection from both infrared (IR) radiation and visible light. UV filters can also optionally be included to provide additional protection from UV light.
