Description
Technical field
The present invention relates to new application of the niacinamide in terms of preventing salivary gland radiation insult, belong to pharmaceutical sanitary field.
Background technique
Niacinamide (Nicotinamide, NAM) is also known as niacinamide, is the amide compound of niacin, is vitamin B3
The component part of Coenzyme I and Coenzyme I I in a kind of derivative and human energy metabolism, shown in structure such as formula (I):
In clinical practice, NAM be used for pellagra, stomatitis, glossitis prevention and treatment, and treatment coronary heart disease, vital myocarditis,
The arrhythmia cordis that rheumatic heart disease and a small number of digitalis poisonings etc. occur together.Currently, existing patent CN106715455A (China)
Describing nicotinamide riboside class medicine can be used for treating the subject for suffering from or being susceptible to suffer from mitochondrial disease or illness, or for increasing
Suffer from or be susceptible to suffer from the insulin sensitivity of the subject of insulin resistance, metabolic syndrome, diabetes or its complication, the disease
Disease or illness will benefit from increased nicotinamide adenine dinucleotide (nicotinamide adenine dinucleotide,
NAD) horizontal.Patent CN101601679A (China) describes drug or health care of the NAM mononucleotide in preparation prevention and treatment cerebral apoplexy
Application in food, illustrating NAM mononucleotide itself is the endogenic Protective substances of body, has very high drug safety.
Salivary gland radiation insult is the common complication of head and neck neoplasm radiotherapy.Clinical manifestation be radiation therapy delivery during and
After radiotherapy, there is serious mouth parched symptom in patient, influences the normal physiological functions such as normal language, the sense of taste, feed, substantially reduces
The quality of life of patient.The damage of salivary gland caused by head and neck neoplasm radiotherapy how is coped with, is clinical problem urgently to be resolved
One of.In recent years, the degree of being showing improvement or progress day by day with radiotherapy technology, salivary gland radiation insult is alleviated, and clinician also exists
Seek some other means to protect the function of salivary gland as far as possible, as the application of artificial saliva, salivary gland transfer operation are opened
Exhibition etc., but these means fundamentally change salivary gland exposure after function reduction the phenomenon that.It has been reported that in animal experiments
Salivary gland radiation insult is treated by the way of gene transfer, obtains certain curative effect, but its effectiveness is ofer short duration, and in a short time
It is difficult to apply in clinic.
Summary of the invention
To solve prior art problem, the present invention provides a kind of niacinamide (NAM) and prevents salivary gland radiation insult in preparation
Drug in application, and have good effect.
Radiation insult of the present invention is radiation insult caused by radiotherapy (radiotherapy).
Radiation insult of the present invention is radiation insult caused by interior radiation and fluconazole ear drops.Internal radiotherapy is
Internal (internal) radiotherapy is that radioactive source is placed in a kind of intracorporal side for the treatment of of body in a variety of manners (including oral or implantation)
Formula, such as radioiodine therapy;Fluconazole ear drops are external (external) radiotherapy, are that clinically usually said radiation is controlled
It treats, is that radioactive source is placed in a kind of extracorporeal therapeutic modality.
The present invention using the rat primary submandibular gland cell of originally culture and Wistar rat as model, through experimental studies have found that
NAM has good prevention radiation insult effect in salivary gland cell and tissue, that is, it is thin to be effectively improved salivary gland caused by radioactive ray
The decline of born of the same parents' vigor, gland tissue structure is destroyed and Apoptosis etc., and can reduce in cellular level discovery NAM radiation-induced
The reduction of acinar cells NAD level.These results of study show that NAM can improve the energetic supersession of irradiated cell, are clinical pre-
Anti- salivary gland radiation injury provides a kind of new method.
The dosage form of the drug of prevention salivary gland radiation insult of the invention can be tablet, capsule, pill, emulsion, injection
Agent, syrup, oral solution, granule or patch.
(1) in cellular level, NAM (50-200 μM) can prevent rat submandibular gland cell radiation injury.
(2) in tissue and organ level, NAM (500mg/kg) can prevent the damage of rat radioactivity salivary gland.
The vigor of originally culture rat submandibular gland cell can be improved in NAM pretreatment of the present invention, reduces saliva after radiation injury
NAD synthesizes rate-limiting enzyme Nampt (nicotinamide in liquid gland cell
Phosphoribosyltransferase, NAMPT) reduction, improve cellular NAD level.To prompt NAM to promote carefully
Born of the same parents' Mitochondria oxidative phosphorylation metabolism and series are using NAD as key protein (such as SIRT1/ of the regulation mitochondria of substrate
PGC-1 α etc.) metabolic activity.Meanwhile the present invention also has found that NAM pretreatment can be improved rat submandibular gland in animal model
The ability of radiation injury is resisted, NAM pretreatment has protective effect to submandibular organization's morphosis in histological level, mitigates
Radiation injury, and significantly mitigate the apoptosis of radiation-induced submandibular gland acinar cells.
Beneficial effects of the present invention:
The present invention finally specifies that NAM can effectively prevent salivary gland radiation insult by cell and zoopery.The present invention
In NAM can be prepared into prevention salivary gland radiation insult drug, for clinical treatment radioactivity salivary gland damage provide one kind
New method.The present invention proposes that the drug containing NAM can generate following effect to the salivary gland of radiation insult:
1. improving acinar cells survival rate after radiation;
2. preventing salivary organization's radiation injury;
3. mitigating the radiogenic Apoptosis of salivary gland.

State observation discovery: NAM pretreated group cell growth state is good, and cellular morphology is close with density with normal cell.
(2) influence of Fig. 2 .NAM to radiation injury submandibular gland cell vigor.* P < 0.05 is compared with blank control group;#P<
0.05 compared with simple irradiation group.Cell viability experiment display: NAM significantly promotes the cell viability of acinar cells after radiation,
To demonstrate the direct effect that NAM promotees salivary gland cell survival after ionization radiation injury.
(3) influence of Fig. 3 .NAM to NAMPT protein expression level in radiation injury submandibular gland cell.Cellular immunofluorescence
As a result prompt: NAM significantly increases the expression of submandibular gland cell NAMPT albumen after radiation, shows NAM to radiation injury salivary gland
The protective effect of cell is related with NAMPT protein upregulation.
(4) influence of Fig. 4 .NAM to radiation injury submandibular gland cell NAD level.* P < 0.05 is compared with blank control group;#
P < 0.05 is compared with simple irradiation group.NAD testing result is shown: submandibular gland cell NAD is horizontal after NAM has significantly raised radiation,
Show that NAM may be related to the mitochondrial approach that NAD is mediated to the protective effect of radiation injury cell.
4. conclusion
NAM can effectively mitigate the damage radiated to submandibular gland cell, and mechanism is that NAM promotes NAMPT synthesis, improve cell
NAD is horizontal, the mitochondrial mediated so as to improve NAD.
Embodiment 2:NAM prevents the experimental study of rat submandibular gland tissue radiation damage
1. purpose
NAM is inquired into the preventive and therapeutic effect of submandibular organization's radiation insult.
