Embodiment 1

[0022] Embodiment 1 contains the capsule of NADPH

[0023] The capsule of the present embodiment comprises following composition:

[0024] NADPH 20g; suspending agent microcrystalline cellulose 60g; preservative tert-butyl-4-hydroxyanisole 0.04g; lubricant magnesium stearate 2g; filler lactose added to 200g.

[0025] Its preparation method comprises the following steps:

[0026] Weigh the NADPH and various pharmaceutical excipients in the above prescription amount, mix them evenly, pass through a 60-mesh sieve three times, and put them into capsules.

[0027] The conventional excipients used in the medicine include but are not limited to one or a mixture of fillers, disintegrants, lubricants, binders, flavoring agents, suspending agents, and preservatives.

[0028] Specifically, the filler can also be replaced with a mixture of one or more of pregelatinized starch, mannitol, chitin, microcrystalline cellulose, and sucrose;

[0029] The disintegrant can also be replaced by o...

[0039] Experimental Example 1 The protective effect of exogenous NADPH on primary cultured endothelial cells HUVEC

[0040] (1) Experimental materials:

[0041] The primary cultured endothelial cells HUVEC cells used in the experiment were purchased from ATCC cell bank in the United States. Cryopreservation conditions: 2ml cryopreservation tubes, 1.6 million cells per tube, containing 70% high glucose DMEM, 20% domestic fetal bovine serum, 10% DMSO.

[0042] (2) Experimental plan:

[0043]Endothelial cell HUVEC culture: culture conditions: 37°C (5% CO2, 95% air), saturated humidity, high-sugar DMEM medium, medium containing 100U penicillin and 100U streptomycin per liter; 10% domestic fetal bovine serum; The cells were grown to about 80-90% confluence, digested with trypsin-EDTA solution and then passaged, passage density: 5×10 5 Each bottle is passaged every 2-3 days; take the logarithmic growth of HUVEC cells, add an appropriate amount of trypsin-EDTA digestion solution t...

[0047] Experimental Example 2 Prophylactic Administration of NADPH Alleviates Blood-brain Barrier-related Immunity After Brain Injury

[0048] cellular response

[0049] (1) Experimental materials

[0050] Clean-grade male ICR mice, weighing 23-28 g, were provided by the Experimental Animal Center of Soochow University, experimental animal production license number: XCYK (Su) 2002-2008, experimental animal use license number: SYXK (Su) 2002-0037. C57BL6 and Tg(Itgax-Venus)1Mnz mice, weighing 22-27g, are male. Tg(Itgax-Venus)1Mnz mice are products of MGI Company. The mice are positive for CD11c-eYFP and are used to study the involvement of dendritic cells in the immune response after brain injury. The room temperature is 22°C, the humidity is 50-60%, the ventilation is good, artificial day and night (12h / 12h), free to eat and drink. Before the experiment, the male mice were acclimatized in the breeding environment for 2 days. Dextran-Texas (Red): product of Invitrogen Compa...

Abstract

The invention discloses application of NADPH in preparation of drugs used for treating or preventing cardio-cerebrovascular diseases. Research results show that NADPH can protect vascular endothelial cells and maintain normal vascular permeability and is a candidate drug used for treating or preventing cardio-cerebrovascular diseases, especially thrombotic diseases, hypertension, coronary heart diseases, vascular sclerosis and vascular sclerosis caused by damage of vascular endothelial cells.

Description

technical field [0001] The invention relates to a new indication of NADPH, specifically the application of NADPH in the preparation of medicines for treating or preventing cardiovascular and cerebrovascular diseases. Background technique [0002] Cardiovascular and cerebrovascular diseases refer to diseases of the heart and cerebrovascular. Cardiovascular and cerebrovascular diseases have the characteristics of "high morbidity, high mortality, high disability rate, high recurrence rate, and many complications" ("four high and one high"), and have become a heavy burden on global health care and health resources , is the number one enemy of the second health revolution. At present, there are more than 270 million patients with cardiovascular and cerebrovascular diseases in my country. Especially after my country enters an aging society, the incidence of cardiovascular and cerebrovascular diseases is still increasing. important task in the medical field. The pathogenesis of c...
