Tumor diagnosis and treatment fluorescent probe for targeting tumor Wolburg effect

The invention discloses a tumor diagnosis and treatment fluorescent probe for targeting tumor Warburg effect, and the structure of the fluorescent probe is shown as a formula (I). The fluorescent probe can be directly used in a cell line to analyze and detect the expression degree of tumor cell GLUT1 protein, so as to complete the screening of tumor cells. Meanwhile, tumor cell proliferation is inhibited by directly blocking the GLUT1 channel to inhibit intake of sugar nutritional ingredients by tumors. And an effective means and a useful tool are provided for early screening and diagnosis oftumors, development of new anti-tumor drugs and the like.

Directing the crystallization of dehydro[24]annulenes into supramolecular nanotubular scaffolds

The self-assembly of a series of dehydro[24]annulene derivatives into columnar stacks has been examined for its latent ability to form -conjugated carbon-rich nanotubular structures through topochemical polymerizations. We have studied the parameters affe

SuFEx-based synthesis of polysulfates

High-molecular-weight polysulfates are readily formed from aromatic bis(silyl ethers) and bis(fluorosulfates) in the presence of a base catalyst. The reaction is fast and proceeds well under neat conditions or in solvents, such as dimethyl formamide or N-methylpyrrolidone, to provide the desired polymers in nearly quantitative yield. These polymers are more resistant to chemical degradation than their polycarbonate analogues and exhibit excellent mechanical, optical, and oxygen-barrier properties.

Construction of segregated arrays of multiple donor and acceptor units using a dendritic scaffold: Remarkable dendrimer effects on photoinduced charge separation

Dendritic molecules appended with multiple zinc porphyrin units (DP m, m [number of zinc porphyrin units] = 6, 12, and 24) trap bipyridine compounds carrying multiple fullerene units (Py2P n, n [number of C60 units] = 1-3), affording coordination complexes DPm?Py2Fn having a photoactive layer consisting of spatially segregated donor and acceptor arrays on their surface. Complexes DPm?Py2Fn are stable enough (K [average binding affinity] = 1.1 × 106-4.4 × 106 M-1 in CHCl3 at 25 °C) to be isolated by gel permeation chromatography. UHV-STM microscopy enables clear visualization of a petal-like structure of DP12?Py2F3. Photoexcitation of the zinc porphyrin units in DPm?Py 2Fn results in a zinc porphyrin-to-fullerene electron transfer to generate a charge separation. The charge-separation rate constant (kCS) in CH2Cl2 at 20 °C increases from 0.26 × 1010 to 2.3 × 1010 s-1 upon increment of m and n, whereas the charge-recombination rate constant (k CR) remains almost unchanged at 4.5 × 106-6.7 × 106 s-1. Consequently, DP24?Py 2F3 furnishes the largest ratio of kCS/k CR (3400) among the family.

Single-crystal-to-single-crystal topochemical polymerizations of a terminal diacetylene: Two remarkable transformations give the same conjugated polymer

Host-guest chemistry was used to prepare a cocrystal of a dipyridyl substituted oxalamide host and a resorcinol derivative of a terminal diacetylene. X-ray crystallography revealed that the molecules assemble into a triple-helix with the diacetylene functionalities aligned in the center of the helix. Upon heating, the diacetylenes polymerize to give the corresponding polymer. In a second experiment, the X-ray structure of the crystalline hydrate of the same diacetylene also showed a suitable alignment of the diacetylene functionalities. These crystals polymerize at only 50 °C with the C1 carbon end of the diacetylene undergoing an unprecedented 2.4 A inward swinging movement. This results in a remarkable 9% increase in crystal density. These are the first structurally characterized polymerizations of any terminal diacetylene. A detailed comparison of the two sets of structural changes offers an interesting insight into the precise trajectories of polymerization reactions. Copyright
