PRESS CONFERENCE : CANSSUFIVE

The press conference was held on  21 October 2009, Wednesday at 11 am at Level 6 Canselory Building at the Universiti Sains Malaysia, Penang Campus.

 

EMAN group of researchers  has succeeded in producing standardised “Misai Kucing” (Orthosiphon Stamineus) herbal extract for the treatment of cancer.This novel  herbal extract is presented in the form of a pill is called CANSSUFIVE. Our group, headed by Dr. Amin Malik Shah has found out that Misai Kucing (literally meaning, Cat”s Whiskers), has high anti-oxidant content that could prevent and control the growth of cancer cells. 

“CANSSUFIVE shows very promising results in breast cancer treatment when given together with chemotherapy,”- Dr. Amin Malik Shah bin Abdul Majid

Dr. Amin said, the Misai Kucing extract named “CANSSUFIVE” was tested on animals and found to retard blood vessel development, thus preventing the cancel cells from spreading to tissues and other organs. He also planned to do clinical study on the effectiveness of Canssufive on humans as soon as possible so that cancer patients and others can get it on the market.

Nahdzatul Syima Binti Muslim

 A Lil Bit About Me:

Syima was born in Alor Star, Kedah in 8th of May 1985; where her family was living back then, before they moved to Kulim due to her mother and father’s work. She happily enjoyed her small town life in Kulim until she completed her high school days in Sekolah Menengah Kebangsaan Sultan Badlishah, Kulim in 2002. Then she continued to study Industrial Chemistry (Diploma) in Universiti Teknologi MARA, Perlis (a small state, yet a great place for cheap but yummy delicacies, lots of places to tour in with unique culture blending in and not to mention the chance to cross the border to Thailand!) until she graduated in September 2006. She went to study for bachelor degree in Applied Chemistry in Universiti Teknologi MARA, Shah Alam (the capital of Selangor with attracting shopping malls, near to KL, Klang, pricey food though) until she graduated in November 2008. Currently she’s a M.Sc student under the supervision of Dr. Amin Malik Shah Abdul Majid and her work involves bacterial work in which she is keen to study the expression of IFN – α in E. coli strains. The production of interferons shall be upscaled using our own 3-L biofermentor. The medium to be used will also be replaced with non – animal based medium. Previously during her undergraduates’ days, Syima had experiences of working with HPLC for her final year thesis. Apart from that, she also had experiences of working with AAS, UV-Vis and GC. Syima enjoys gardening around her family house, playing with her cats, playing games, watching movies and listening to music to fill in her free time. Syima is now residing in Seberang Jaya, Pulau Pinang with her family.


Research Interest:

I’m interested in expressing interferon – α using E. coli as the host and cloning the protein so that greater amount of the protein can be produced using a biofermentor. In order to do so, we need to setup the most suitable operating conditions, so that to ensure highest yield and purity of protein can be achieved. The media that will be used in the study will also be replaced with non – animal based media. In this study, interferons is the proteins of interest because interferons generally have the potential of anti – viral, anti – tumor and immunomodulatory activities, which in turn will enables them to be used as therapeutic agents (Nagamine et al, 2009). For these reasons, we are interested in expressing the stated protein, so that if we are capable to produce the product in greater amount, it might have potential to be combined with other kind of drugs to serve as therapeutic agents. We are also interested in optimizing the operating conditions of the biofermentor since it affect cell cultivation performance, and also gene expression. The knowledge of the biofermentor can then be applied in cultivating other types of cells in future.

BIOREACTOR TRAINING

On 6th and 7th of August 2009, a workshop on Bioreactor Operation was held in Physiology Teaching Laboratory, School of Pharmaceutical Sciences, Universiti Sains Malaysia. The workshop was organized by Pharmacology and Physiology Department, School of Pharmaceutical Sciences; USM in collaboration with Intran Technologies Sdn. Bhd. Intran Technologies Sdn. Bhd. is the company who supplied and maintained the bioreactor unit owned by the school.

15 participants whom were postgraduate students from School of Pharmaceutical Sciences, School of Biological Sciences, INFORMM and also Malaysian Institute of Pharmaceuticals and Nutraceuticals (iPHARM) participated in the two days workshop. In addition, there were 5 staffs from Intran Technologies Sdn. Bhd., who joined the workshop. The facilitator of the workshop was Mr. Mohd Rizal, a bioprocess expert from Universiti Putra Malaysia.

The workshop conducted involved lectures of theories and explanation regarding the bioreactor unit and components and their respective functions. The facilitator also conducted the workshop in laboratory session, to give deeper explanation about the bioreactor unit and its components to the participants, so as to increase participants’ understanding regarding the theories given in lectures. The facilitator did also show the basic operation of the bioreactor unit during the laboratory session. The bioreactor unit used in this workshop was of 3L working capacity. The bioreactor unit used as the model for this workshop is the unit which is currently located in Immunopharmacology Laboratory (J02-119).

Research Interest:

Cancer is fatal disease that is affecting one in every five Malaysians. The treatment success varies considerably with early detection being the most important factor. Chemotherapy is the mainstay for cancer treatment but it can cause adverse side effects and is highly unaffordable particularly the more modern drugs. The main aim of our research activity is to find cheap anti-tumor agents that also have fewer side effects.

We are interested in natural products that cause inhibition in blood vessel development, a process commonly referred as antiangiogenesis. This process is vital for tumor growth and is the key step for metastasis. Antiangiogenic agents are generally non-cytotoxic hence have fewer side effects. One of the emerging techniques in treating cancer is to couple antiangiogenic agents with classical chemotherapy. This has shown marked improvement in prolonging survival of cancer patients. The new antiangiogenic drugs however, are unaffordable to the general public. With the aid of the NaPIMM molecular modeling software package developed in USM by Habibah Wahab and coworkers, our team identified a series of plants that have compounds which can target the VEGFR2 receptor, a key receptor in angiogenesis pathway. By using an ex-vivo 3-Dimensional tissue culture technique, we screened standardized extracts of the potential plant short listed in NaPIMM for any antiangiogenic activity. We identified Bitter melon, Nutmeg and Misai Kucing to be amongst the most active plant species. We were able to distinguish the solvent system that gave the strongest response and the optimum dose required. We are currently co-administering classical chemotherapy agents with these extracts to see any synergistic activity in vitro and in vivo tumor models. We are also interested in looking at the genes that are being perturbed by co-administration of these extracts with classical chemotherapy drugs in the angiogenesis and carcinogenesis pathways. In the out set of this work, we are interested in how chemotherapeutic agents interact with the nucleic acid. By employing mass spectrometry machines, we are able to pin point the exact location of drug binding on the DNA. This information helps us to better design chemotherapeutic agents that interact with the DNA in a more sequence specific manner. We are currently developing a peptide based molecule that targets the hypoxic responsive element which activates VEGF. We hope this molecule is able to demonstrate potent antiangiogenic response.

Muath Hekmat Helal

A Lil Bit About Me :

Muath was born and grew up in small village surrounded by olive and orange trees named Qalqilia, Palestine. He graduated form Pharmacy school from the An-Najah National university in 2007. He joined Pharmacology department at Universiti Sains Malaysia in 2007 under the supervision of Dr. Amin Malik Shah Abdul Majid. During his master work, he had to work with different techniques and machines such as spectroscopy, cytotoxicity, and angiogenesis. He was more interested furthering his studies, therefore he proceeded with his master directly after graduation. He was awarded a scholarship from Malaysian Government during his Master studies. His research area is in Cancer pharmacology and focused on DNA and DNA-binding agents for treatment. Here, he lives happily in lovely-flat nearby in Penang.

Research Interest:

I am interested in studying DNA binding compounds. My main purpose for these is cancer treatment, but keeping in mind viral treatment as well. For the past several decades DNA has been the main target for cancer treatment. Unfortunately, these compounds tend to cause side effects including cancer. The main reason for causing side effects is the lack of sequence selectivity. These compounds do not have the ability to discriminate between DNA sequences. I am interested in studying the mechanism of how these compounds tend to bind with DNA in order to modify or synthesis new compounds that would have better sequence specificity. I am also interested in gene therapy as a potential cancer treatment method. Although peptide compounds might have better selectivity, it is known to have some difficulties in administering the products to human body.

Research Interest:

Development of tumors is a highly complex process in which several molecular events are required for tumor cells to achieve independent growth. One such event is the enhancement of angiogenesis. Angiogenesis is the formation and growth of new blood vessels. It occurs in the healthy body for healing wounds and for restoring blood flow to tissues after injury or insult. Therefore angiogenesis is a necessary component of normal tissue repair, tumor growth and a wide variety of other inflammatory and pathological process as well. The normal healthy body maintains a perfect balance of angiogenesis modulators. For this reason, antiangiogenic therapies aimed at halting new blood vessel growth are being developed to treat diseases that involves angiogenesis such as cancer, diabetes retinopathy and rheumatism to name a few.

Mixtures of interacting compounds produced by plants may provide important combination therapies that concurrently have an effect on multiple pharmacological targets and provide clinical effectiveness beyond the reach of single compound-based drugs. The chemotherapeutic agents can be combined with botanical therapeutics, the plant-produced compounds which are used to treat and prevent diseases or maintain health and wellness.

Mitragyna speciosa or locally known as ketum was found to contain various alkaloids which makes it useful in the treatment of hypertension and boost the immune system. It was also found to contain some antioxidant compounds, which usually tend to have antiangiogenic properties. From the molecular modeling packages, the results showed that the plant product exhibits the antiangiogenic activity. For that reason, my work is to prove that the plant product is antiangiogenic and if so, to determine the mechanism that synergize the activity on how these extracts would be beneficial to perturb tumor growth.

Research Interest:

My project about the benzimidazole derivatives and their anticancer activity. As we know that the benzimidazole had wide biological activities like anti-inflammatory, antibacterial, antihypertensive and others. Also it’s well known anticancer agents due to their good topoisomerase I inhibiting action and DNA binding activity. DNA-topoisomerases are enzymes present in the nuclei of cells where they catalyze the breaking and rejoining of DNA strands hence controlling the topological state of DNA. Recent studies also suggest that topoisomerases are involved in regulating template supercoiling during RNA transcription. The antitumor activity associated with agents which are topoisomerase poisons is associated with their ability to stabilize the enzyme-DNA cleavable complex. This will prevent DNA proliferation which is an important stage in the growth of the cancer cells.
