Article Synopsis
  • Heparin is effective in reducing heart damage from ischemia/reperfusion (I/R), but its strong blood-thinning properties limit its clinical use.
  • A specific derivative, 6-O-desulfated heparin, shows lower anticoagulant effects and can protect against myocardial I/R injury, as evidenced by reduced heart damage and cell death in animal studies.
  • The protective mechanism involves influencing specific molecules (miR-199a-5p and klotho) and reducing harmful reactive oxygen species, making 6-O-desulfated heparin a promising therapeutic option for heart injury.

Control of photoinduced electron transfer through selective excitation of a π-conjugated diblock oligomeric system featuring tetrathiophene (T) and tetra(phenylene ethynylene) (PE) donor blocks capped with a naphthalene diimide (NDI) acceptor (TPENDI) is demonstrated. Each π-conjugated oligomeric segment has its own discrete ionization potential, electron affinity, and optical band gap which provides an absorption profile that has specific wavelengths that offer selective excitation of the PE and T blocks. Therefore, TPENDI can be selectively excited to form a charge-separated state via ultrafast photoinduced electron transfer from the PE segment to NDI when excited at 370 nm, but it does not produce a charge-separated state when excited at 420 nm (T).

A series of π-conjugated oligomer-acceptor dyads were synthesized that feature oligo(phenylene ethynylene) (OPE) conjugated backbones end-capped with a naphthalene diimide (NDI) acceptor. The OPE segments vary in length from 4 to 8 phenylene ethynene units (PEn-NDI, where n = 4, 6 and 8). Fluorescence and transient absorption spectroscopy reveals that intramolecular OPE → NDI charge transfer dominates the deactivation of excited states of the PEn-NDI oligomers.

The interactions of two anionic poly(phenylene ethynylene) sulfonate-conjugated polyelectrolytes (mPPESO and pPPESO) with two alkynylplatinum(II) terpyridine complexes (Pt and Pt) were studied. The Pt(II) complexes interact with helical mPPESO by intercalation within the polymer helix to form a "guest-host" ensemble. Titration of Pt(II) complexes into an aqueous solution of mPPESO gives rise to efficient quenching of the polymer's fluorescence; meanwhile, triplet metal-metal-to-ligand charge transfer (MMLCT) state emission from the intercalated Pt(II) complexes appears when the ensembles are excited into the polymer's absorption band.
