  • Thiourea-containing dendrimer and thiourea-containing hyperbranched polymer as well as preparation methods thereof and applications thereof
    Patent number: 10072125
    Abstract: The present invention discloses thiourea-containing dendrimers and thiourea-containing hyperbranched polymers, and respectively a preparation method for the thiourea-containing dendrimer and a preparation method for the thiourea-containing hyperbranched polymer, and a thiourea-containing dendrimer and a thiourea-containing hyperbranched polymer having increased water solubility prepared by using the thiourea-containing dendrimer and the thiourea-containing hyperbranched polymer as raw materials. Finally, disclosed are applications of the thiourea-containing dendrimers and the thiourea-containing hyperbranched polymers in the preparation of antitumor and antimicrobial drugs. The thiourea-containing dendrimer and the thiourea-containing hyperbranched polymer have a significant growth inhibitive effect on solid tumors and low toxicity to normal tissues, and thus can be used for preparing drugs for treating malignant tumors.
