欧美口爆视频 Cancer Center leaders aim to use novel molecule to fight cancer
Tin Tin Su of 欧美口爆视频 Boulder and Antonio Jimeno of the 欧美口爆视频 School of Medicine say acceleration-initiative funds will help speed a promising, developed-in-欧美口爆视频 cancer therapy to patients
After working eight years on a new way to attack some cancers, a pair of researchers are closer to their goal of bringing their therapy to patients鈥攁s one of nine research endeavors receiving funding from the (AAI).
The project is led jointly by Tin Tin Su, co-leader of the cancer center鈥檚 and professor of molecular, cellular and developmental biology at the University of 欧美口爆视频 Boulder, and , a co-leader of the 欧美口爆视频 Cancer Center鈥檚 and professor in the 's .
Tin Tin Su, a 欧美口爆视频 Boulder professor of molecular, cellular and developmental biology, discovered that a molecule found in the firecracker bush can be synthesized to target cancer stem cells.
Jimeno says it鈥檚 significant that the AAI award is for a potential cancer therapy 鈥渢hat was discovered in 欧美口爆视频 and will use 欧美口爆视频 funds from a 欧美口爆视频 donor to help 欧美口爆视频 cancer patients.鈥
He adds: 鈥淗ere at the 欧美口爆视频 Cancer Center, we can get things done really well and really quickly, provided we have the focus and the resources. And this grant provides both.鈥
Their work involves the use of a synthetic small molecule called SVC112, which has been shown to effectively target cancer stem cells in , the main focus of Jimeno鈥檚 .
Cancer stem cells produce cells that make up most of a tumor鈥檚 bulk. They often are resistant to traditional therapies such as radiation and chemotherapy and can recover from treatment to produce more tumor cells. The U.S. Food & Drug Administration has approved the use of protein synthesis inhibitors that slow or stop cancer cell growth, but they can be toxic to healthy cells as well as cancer cells.
SVC112 was originally synthesized by SuviCa, Inc., a Boulder-based biotechnology company co-founded by Su. It鈥檚 based on the chemical bouvardin, found in the firecracker bush, Bouvardia ternifolia, a red-flowering plant that grows in the Southwest and Mexico.
The discovery in Su鈥檚 research lab at 欧美口爆视频 Boulder of bouvardin鈥檚 remarkable ability to prevent regeneration of tissues in the fruit fly led to the current studies.
Previous research by Jimeno, Su, and others showed that SVC112 can keep cancer stem cells from manufacturing more tumor cells. The pre-clinical research indicated that SVC112 can be more effective than the FDA-approved protein synthesis inhibitor homoharringtonin (HHT), and with less toxicity, while also increasing the effects of radiation treatment.
鈥淚t鈥檚 effective in ways that other drugs are not,鈥 Su says. 鈥淭his compound has shown efficacy in squamous head and neck cancer, in salivary gland cancer, colorectal cancer, and leukemia models. This is very exciting, because it proves the biologic point that multiple tumor types rely on the same mechanisms, the same proteins, to become invasive, to grow and to metastasize.鈥

Su points out that SVC112 passed three reviews to be approved to receive milestone-based support from the National Cancer Institute鈥檚 (NCI) in 2023, providing resources for SVC112鈥檚 development. NCI is part of the National Institutes of Health.
Jimeno says that the five-year AAI grant will help fund the arduous next steps in developing SVC112. First, the researchers will conduct pre-clinical experiments leading to an investigational new drug filing to the FDA within two years. Next, he says, plans call for a first-in-human Phase 1a in cancer patients 鈥渢o determine the safe, optimal way of delivering this to humans, employing all the clinical-trials capabilities of our university, including the ,鈥 followed by a Phase 1b trial.
Cancers to be targeted in later stages of the clinical trials may change based on early results, if the researchers see patients with certain cancers responding especially well, Jimeno says.
The AAI recipients were announced in January by 欧美口爆视频 School of Medicine Dean John J. Reilly, Jr., MD, during his annual .
