Summary: Scientists have discovered that a molecule called kalata B1, found in violets, can significantly enhance the effectiveness of the chemotherapy drug Temozolomide ( TMZ) in treating glioblastoma. In laboratory tests, this manufactured molecule increased the amount of TMZ needed to kill cancer cells by over twofold.
Experts believe that the synthetic version of kalata B1, which mirrors the normal material’s structure, could be a potential discovery in glioblastoma care. Although the finding is encouraging, the group emphasizes that clinical trials are still in the future.
Important Information:
- Kalata B1, derived from flowers, enhances chemotherapy’s success by twofold.
- In terms of composition and effectiveness, synthetic kalata B1 resembles the natural molecule.
- The next step is to test mouse models before attempting to conduct medical studies.

One of the most severe head conditions known is glaublastoma. More than 45 % of brain tumors are cancer.
The FDA-approved chemotherapy Temozolomide ( TMZ) is only effective in half of glioblastomas patients. Even for those people, the cancer tissues quickly evolve weight.
Most people pass away within 12 to 16 weeks after treatment, and some make it beyond five ages.
A glimmer of hope for people comes from Jackson Hole, Wyoming, where researchers from the non-profit Head Chemistry Labs have been studying the compounds found in flowers.
A stunning collection of tiny circular peptides, or cyclotides, are produced by violets. They almost appear in design “like floppy baseballs”, says Dr. Samantha L. Gerlach. They have been demonstrated to be effective in the lab against a number of different types of human cancer cell.
The formation of pores in the membranes of cancer cells may be aided by the maintainance of the form of cyclotides by covalent crosslinks. Within the flower, cyclotides provide security against insect animals, bacterial infections, and viruses.
Cyclotides were first discovered in an herbal tea that indigenous people in Africa used to speed up pregnancy. The drink was made from a shrub they call kalata-kalata and which experts call , Oldenlandia lepidoptera.
The cyclotide kalata B1 boosts the action of the treatment Fox, reducing the amount needed to kill glioblastoma cells by over tenfold, according to a team of international scientists from Jackson Hole’s Jackson Hole. Dr. Gerlach and her coworkers demonstrated that a chemical version of kalata B1 has the same level of performance as a real protein.
” While kalata B1 typically occurs in violet species, separation from plant material produces only miniscule portions”, Gerlach state.
The few grams we can get are inappropriate for scientific research, according to the worker who works day and night for months.
The researchers were able to get much larger amounts of the chemical version in sufficient quantities for tests in mouse models of glioblastoma thanks to a cooperation with CSBio in California.
It was discovered that the chemical kalata B1’s structure and effectiveness were completely equal to the natural molecule. The shape and folding of the synthetic molecule were confirmed by Dr. Krish Krishnan of California State University, Fresno using Nuclear Magnetic Resonance ( NMR ) spectroscopy.
Our body data points to the possibility of developing the chemical version in animals models, according to Dr. Rachael Dunlop of the Brain Chemistry Labs. This second stage of testing in animals will appear in Vienna, Austria.
Dr. Paul Alan Cox, director of Brain Chemistry Labs, is skeptical about overstating the value for people, but he does think the introduction of artificial kalata B1 may be a significant step forward.
” We are also a way to go from clinical trials, but it’s time to assess whether it might be healthy for us to continue testing.”

Abstract
Kalata B1 Increases Glioblastoma Cells ‘ Temozolomide Poisoning
Glioblastoma ( GBM ) is the most aggressive cancer originating in the brain, but unfortunately combination treatments with resection, radiation, and chemotherapy are relatively ineffective. So, novel methods of antidepressant therapy are thoroughly needed.
Cyclotides are plant-derived round proteins that chemosensitize drug-resistant shoulder cancer to chemotherapy.
We analyzed human glioblastoma cells using temozolomide ( TMZ) alone and in combination with naturally occurring and synthetic cyclotides ( Cycloviolacin O3, Cycloviolacin O19, natural Kalata B1, synthetic Kalata B1, and Vitri E).
The cyclotides were identified by UPLC-PDA and HPLC-UV. NMR spectroscopy provided architectural confirmation, and orbitrap LC-MS was used to verify the artificial Kalata B1 sequence.
The cyclotides displayed dose-dependent cytotoxicity ( IC50 , values 2.4–21.1 µM ) both alone and as chemosensitizers of U-87 MG and T 98 cells to TMZ. In fact, a 16-fold lower concentration of TMZ ( 100 µM ) was needed for significant cytotoxicity in U-87 MG cells co-exposed to synthetic Kalata B ( 0.5 µM ).
Similarly, a 15-fold lower concentration of TMZ ( 75 µM ) was required for a significant reduction in cell viability in T 98 cells co-exposed to synthetic Kalata B1 ( 0.25 µM ). In human blood balance tests, kata B1 continued to be firm. The evidence backs up the claim that cyclotides perhaps lysate TMZ-derived glioblastoma cells.
