Key to future Alzheimer's treatment lies in the past

A Hong Kong Baptist University research team has successfully used the Huang Lian Jie DuTang (HLJDT) to treat the symptoms

and reverse some of the neurological changes of one of thekey causes of dementia. Its potential for commercial use is significant.


Hong Kong researchers are hunting for a significant breakthrough in the treatment ofAlzheimer's disease by studying traditional Chinese medicine.

Research into the ingredients used in a traditional Chinese medicine may offer new hope tosufferers of Alzheimer's disease and other degenerative brain disorders.

A Hong Kong Baptist University research team is looking into the use of Huang Lian Jie DuTang (HLJDT) to treat the symptoms and reverse some of the neurological changes of one ofthe key causes of dementia.

Professor Li Min and her team from the School of Chinese Medicine have modified the traditional formula of HLJDT for detoxification and removing heat from the body, and demonstrated that the modified formula can significantly remove the aggregation of proteins and the amino acids called Amyloid beta, which are commonly found in the brains of sufferers of Alzheimer's.

Prior research found that HLJDT had significant positive effects in treating inflammation, inadequate blood supply or cerebral ischemia, and tumours. From the technical point of view, their modified HLJDT gives greater therapeutic and pharmacological benefits in the treatment ofAlzheimer's - with minimal side-effects.

Dr Alfred Tan, head of knowledge transfer office of Hong Kong Baptist University, has a mission to enable knowledge transfers through the community engagement such as facilitating the collaborations between the university and industry. Dr Tan described that Alzheimer's and Parkinson's disease are two of the most prevalent neurodegenerative diseases in the world, and the HLJDT research was significant given the prevalence of ageing and genetically-linked disorders among elderlies.

According to statistics, the prevalence of Alzheimer's for those aged over 60 ranges from 5 to 7 per cent worldwide. It was estimated that 35.6 million people lived with dementia worldwide in 2010, with numbers expected to almost double every 20 years to 65.7 million in 2030. For Parkinson's, there are about 10 million patients worldwide, whereas six million patients are in China. Moreover, for 2015, over 9.9 million new cases of dementia each year worldwide, implying one new case every 3.2 seconds is estimated (source:

Dr Tan mentioned that the current treatments for both Alzheimer's and Parkinson's produce only mild, symptomatic relief and do not halt progression of dementia. For example, just five drugs have been approved by the United States Food and Drug Administration for use by neurologists for the management of Alzheimer's. Since there is no cure for Alzheimer's disease at the moment, once the modified HLJDT is registered as a drug, it would bring in tremendous income.

Dr Durairajan SSK from Prof Li's team has been recognized by a grant from the Health and Medical Research Fundprovided by Hong Kong's Food and Health Bureau. The funding supports in vivo research into the HLJDT compound, which the team call NeuroDefend, and its therapeutic effects when used in combination with metamine.

Besides, a HK$5-million donation received in January has been used to establish a research centre at the School of Chinese Medicine to support the study in pharmaceuticals derived from traditional Chinese medicines.

Recently, Prof Li and her team are being engaged in a pharmaceutical company to co-develop herbal supplements which may help protect the human nervous system from the damage caused by ageing.

Dr Tan believed that there were potentially broader applications for Professor Li's research beyond treating Alzheimer's.

"The next goal is to extract several major monomers in the formulation and create a new drugin molecular size for the treatment of Alzheimer's disease through the investigation of molecular interactions," Prof Li said.

The patent for Prof Li's HJDT is currently assigned to the university and has not yet been licensed out but Dr Tan acknowledged the potential was huge.

The university's Knowledge Transfer Office plays a crucial role; for example, assisting in the protection of the university's intellectual properties and commercialisation of inventions and seeking new partnerships.

The patent is currently available on the Asia IP Exchange, a free online platform and database showcasing intellectual properties around the world. Owned and managed by the Hong Kong Trade Development Council, the platform has more than 25,000 tradable IP listings, and its goal is to promote international IP trade and connect global IP players.

"The ever-growing number of patients afflicted by Alzheimer's and Parkinson's triggers the development of new drugs by many of the big pharmaceutical companies," Dr Tan said.

"Once a drug with high efficacy is developed, it would bring enormous impacts to the society and economy."
