Abstract: A mesoporous silica nanoparticle controlled release system, a preparation method thereof and an application thereof, and specifically provides a mesoporous silica nanomaterial that can be used for controlled release is disclosed. The mesoporous silica nanomaterial that can be used for controlled release comprises a mesoporous silica nanoparticle functionalized by means of a polyhydroxy compound and a nanoparticle plugging agent functionalized by means of a phenylboronic acid compound. When substrate concentration is relatively low, the nanomaterial achieves “zero early release”; when substrate concentration is relatively high, mesoporous pores blocked by the plugging agent are opened and active ingredients are released. The nanomaterial can be loaded into microneedles and microneedle array patches used to treat diabetes or to control blood sugar levels in patients.

Abstract: The present invention provides a compound as represented by formula I, or a pharmaceutically acceptable salt or ester, a prodrug, an optical isomer, a stereoisomer, or a solvate thereof. The compound provided by the present invention can be used for preparing drugs for preventing or treating hypertension, or hypertension-related diseases, or pulmonary hypertension, or pulmonary hypertension-related diseases. The compound provided by the present invention has a different mechanism from existing drugs for treating hypertension and pulmonary hypertension, thereby laying a new material foundation for the development of drugs for treating hypertension and pulmonary hypertension.

Abstract: The present invention discloses nitromethylene derivatives and the uses thereof. These derivatives are obtained by adding ring structure onto the known nitromethylene compounds, by which both their stability for light and their liposolubility are increased. Furthermore, by using the substituents linked to ether bond, the steric orientation of the nitro group and the liposolubility of the compounds are controlled. The insecticidal activity tests show that the compounds and their derivatives of the invention display high efficiency on killing various destructive insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hopper, thrips and white fly.

Abstract: The invention discloses novel sulfur-containing naphthalimide derivatives, and the preparation and uses thereof. The conjugated plane of naphthalimide derivatives of the invention is enlarged by incorporating 5-or 6-membered heteroaromatic ring and/or introducing S heteroatom, thus increasing the anti-tumor activity of naphthalimide. The compounds of the invention displays significant inhibiting activities to the proliferation of various tumor cells such as human lung cancer, gastric cancer, liver cancer, leucocythemia and the like. The inhibition of cell proliferation is dose-dependent.

Abstract: The present invention discloses a kind of nitromethylene derivatives as well as their preparation method and their uses. The insecticidal activity tests show that the nitromethylene derivatives of the present invention not only show high insecticidal activities against insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hopper, thrips and white fly and their resistant strains, but also show high insecticidal activities against Lissorhoptrus oryzophilus, carmine spider mite, and they can also be used to prevent sanitary pest, and white ant.
