ANTIVIRAL ACTIVITY OF MEROCYANINE 540

Photochemistry and Photobiology, 1987
Abstract Simultaneous exposure to the lipophilic dye merocyanine 540 (MC 540) and white light inactivates several enveloped viruses. The same treatment appears to have little or no effect on pluripotent hematopoietic stem cells, mature red cells, and mature leukocytes. At least some components of the clotting system are spared, too. The molecular basis

Merocyanine interaction with phosphatidylcholine bilayers

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1993
Merocyanine (MC 540) is a fluorescent probe whose optical properties depend on the environmental polarity. In the presence of lipid bilayers, MC 540 binds to the membrane surface while simultaneously changing its fluorescence properties. Previous studies have shown that the fluorescence of merocyanine depends upon the lipid packing in the membrane.

Merocyanine Dyes with Improved Photostability

Organic Letters, 2007
Merocyanine dyes have proven valuable for live cell fluorescence imaging applications, but many structures have been limited by rapid photobleaching. We show that photostability is substantially enhanced for merocyanines having a cyano group at a specific position in the central polymethine chain.

Merocyanine and Photomerocyanine Dyes

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2000
Abstract We give a review of results from work on merocyanines (MC) and photomerocyanines (PMC) reporting the most stable isomeric forms from X-ray structural and NMR spectral analysis. We also give new X-ray data, 1H-1H NOESY, 1H and 13C-NMR results for MC's.

Merocyanine organic solar cells

Journal of Applied Physics, 1978
Recently, we reported on the development of a new thin-film organic solar cell with an AM1 sunlight efficiency of about 0.7% for large area devices (∼1 cm2). This relatively high-efficiency MIS-Schottky barrier-type cell was based on merocyanine type photosensitizing dyes.

Photocontraction of Liquid Spiropyran-Merocyanine Films

Science, 1984
Amorphous films of a photochromic spiropyran containing a mesogenic group melt, when exposed to heat together with irradiation, to yield a red fluid. This fluid contains aggregates of merocyanine molecules and exhibits marked contraction under light illumination.

Merocyanine-paclitaxel conjugates for photothermal induced chemotherapy

Journal of Materials Chemistry B, 2021
Merocyanine-paclitaxel conjugates could form stable nanoparticles, which indicate the enhanced chemotherapy upon irradiation because of the photothermal effect.

Soluble and stable alternating main-chain merocyanine copolymers through quantitative spiropyran–merocyanine conversion

Polym. Chem., 2014
A combined experimental and theoretical study on the synthesis and solution isomerization behavior of main chain copolymers with multiple spiropyran incorporation is presented. A series of alternating copolymers P(SP-alt-Cx) of spiropyran (SP) and flexible linkers (Cx, x = 6,8,10) is synthesized by Suzuki polycondensation (SPC).

Protein damage by photoproducts of merocyanine 540

Free Radical Biology and Medicine, 1992
Exposure of certain photoactive dyes to light prior to their use in biological systems (preactivation) has been shown to result in formation of long-lived cytotoxic photoproducts. The cytotoxic species responsible for the biological activity of preactivated merocyanine 540 (pMC540) appears to be a hydroperoxide generated by oxidation of ground-state ...
