The entire texts of these two prior applications are incorporated herein by reference. Technical Field
[0002] The present invention relates to the technical field of photosensitizer drug photodynamic antibacterial technology, and more specifically to a hypocrellin derivative, a preparation method and application thereof. Background Art
[0003] Antimicrobial drugs generally refer to drugs with bacteriostatic or bactericidal activity. Since the discovery of antimicrobial drugs such as penicillin, they have effectively treated a wide range of bacterial infections. However, due to the overuse of antibiotics and the approaching "post-antibiotic era," bacterial resistance has become a significant threat to global human health. Therefore, there is an urgent need to identify new drugs and approaches that can effectively alleviate this problem. Photodynamic therapy (PDT) is a rapidly developing new broad-spectrum antimicrobial and tumor treatment technology in recent years. Due to its advantages such as excellent selectivity, minimal toxicity and side effects, minimal invasiveness, broad antitumor spectrum, good applicability, easy elimination of latent cancer lesions, repeatable treatment, and minimal side effects, it has become one of the most promising treatments for drug-resistant bacterial infections. During PDT, a photosensitizer absorbs photon energy under illumination, transitioning from the ground state to a singlet excited state, and then to a triplet excited state via intersystem crossing. Photosensitizers in the triplet excited state can generate reactive oxygen species (ROS) through two mechanisms: (1) the photosensitizer molecules in the triplet excited state undergo electron transfer or hydrogen abstraction reaction with the solvent or substrate to form free radicals or cation or anion radicals, which then combine with oxygen to produce hydroxyl radicals or superoxide anions; (2) energy transfer occurs between the photosensitizer molecules in the triplet excited state and oxygen to produce singlet oxygen ( 1 O2). The generated ROS react with the bacterial membrane or biomacromolecules within the bacteria, inducing bacterial death. The interaction between a suitable light source, a photosensitizer, and oxygen is the three main factors in achieving PDT, with the photosensitizer being the key factor influencing PDT's effectiveness.
[0004] Although existing photosensitizers, such as first-generation photosensitizers hematoporphyrin derivatives; second-generation photosensitizers porphyrins, phthalocyanines, and perylenequinones, have excellent photodynamic antibacterial effects on Gram-positive bacteria, most photosensitizers have poor solubility and, more importantly, limited photodynamic antibacterial effects on Gram-negative bacteria. The main reasons are: compared with Gram-positive bacteria, the thicker outer membrane structure of Gram-negative bacteria hinders the entry of photosensitizers into the bacteria, and the lifespan and distance of ROS generated by photosensitizers under light conditions are very short, making it impossible to effectively perform photodynamic therapy on Gram-negative bacteria. In recent years, researchers have adopted methods such as (1) introducing cations into photosensitizers through chemical modification; (2) co-assembling photosensitizers with cationic polymers; and (3) combining photosensitizers with cationic antimicrobial peptides to improve the problem of poor efficacy against Gram-negative bacteria.
[0005] Hypocrellin is a natural photosensitizer extracted from Hypocrellin, a parasitic fungus found on the arrow bamboo at an altitude of 4,000 meters on the Yunnan Plateau in my country. It has been used as a traditional Chinese medicine for centuries, boasting benefits such as clearing heat, detoxifying, and dispelling carbuncle. Its main components include Hypocrellin A (HA) and Hypocrellin B (HB). As a second-generation photosensitizer, Hypocrellin offers advantages such as easy extraction, high singlet oxygen yield, rapid metabolism, and no side effects. However, its hydrophobicity limits its application in photodynamic therapy. Furthermore, like most photosensitizers, Hypocrellin exhibits excellent photodynamic antibacterial activity against Gram-positive bacteria but is unable to effectively kill Gram-negative bacteria. Although numerous chemical modifications of Hypocrellin have been conducted over the past decade, amphiphilic Hypocrellin derivatives with long wavelengths (600-700 nm) have been developed. However, the currently prepared hypocrellin derivatives still face the problem of poor photodynamic efficacy against Gram-negative bacteria. Therefore, it is of great research significance to prepare new hypocrellin derivatives to improve their bacterial targeting and enhance their photodynamic antibacterial effect.

DETAILED DESCRIPTION
[0207] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and drawings. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.
[0208] In the present invention, the experimental methods described are conventional methods unless otherwise specified. The raw materials used are all available from public commercial sources unless otherwise specified. The percentages described are by mass unless otherwise specified. The M described is mol / L unless otherwise specified.
[0209] The method for testing the minimum inhibitory concentration (MBC) of anti-negative bacteria-Escherichia coli in this application is:
[0210] The minimum inhibitory concentration of the derivatives was evaluated using the plate spreading method using Escherichia coli as an example.
[0211] (1) Bacterial culture: Pick a single colony of Escherichia coli in 50 mL LB medium and culture at 37°C and 220 rpm for 18-24 h. Measure OD600 = 1 (default 2x10 9 CFU mL -1 );
[0212] (2) Add photosensitizer: dilute with saline or PBS to the desired concentration (1x10 5 CFU mL -1 For example, different concentrations of photosensitizing drugs were added to 1 mL of bacterial suspension, and the mixture was incubated at 37°C for 2 h.
[0213] (3) Illumination: For the illumination group, a 532 nm or 635 nm laser (100 mW cm) was used during the culture period. -2 ) Continuous irradiation for 15 minutes.
[0214] (4) Plate spreading: Bacteria were collected by centrifugation (8000 rpm, 5 min), diluted 100-fold with saline, and 100 μL of the E. coli suspension was evenly spread on LB agar plates and cultured at 37°C for 12-16 h until colonies formed.
[0215] (5) Counting: The bacterial survival rate was calculated by comparing the colony counts in the sample treatment group with those in the saline control group.
[0216] The test method for the minimum inhibitory concentration of several other bacterial species (Pseudomonas aeruginosa, Proteus, Salmonella typhi, Bordetella pertussis, Salmonella, Klebsiella, Neisseria meningitidis, Staphylococcus aureus) is basically the same as that for the negative bacteria - Escherichia coli.
[0217] The method for testing the generation of reactive oxygen species in this application is:
[0218] (1) ESR test method, using TEMP as the capture agent:
[0219] Add 10 μL of singlet oxygen capture probe TEMP to 100 μL of HB-3-4N + (1 mM) solution, and the mixture was placed in a 0.1 W cm - 2 , 532nm laser irradiation. The changes in the signal peak were recorded using an electron paramagnetic resonance spectrometer. The test results are shown in Figure 3.
[0220] (2) Chemical capture method, using ABDA as the capture agent:
[0221] HB-36-N + HB-36-2N + and HB-36-4N + The absorption of the aqueous solution at 635 nm was diluted to 0.2. 20 μL, 1 mg mL - 2 Add the ABDA solution of the above dilution solution. Place the mixed solution in 0.01W cm -2 The sample was irradiated with a 635nm laser. The absorption of ABDA was recorded every 30 seconds. The test results are shown in Figures 5 and 6.
[0222] The test method for bacterial imaging in this application is:
[0223] After centrifugation of E. coli culture, the supernatant was discarded, washed three times with physiological saline and diluted to 10 8 CFU mL -1 . Respectively with HB, HB-2-N + HB-2-2N + HB-2-4N +After 3-9 hours of co-incubation, centrifuge and discard the supernatant, wash three times with physiological saline until no obvious color is found, redisperse in physiological saline, drop into a confocal dish (or slide), and photograph using a laser confocal microscope.
[0224] The cytotoxicity test method in this application is the MTT method (anti-tumor effect test, cell half-inhibitory concentration IC 50 ):
[0225] A certain concentration of HeLa cells were seeded in a 96-well plate and cultured at 5% CO2 and 37°C for 24 hours. Then, different concentrations of the test substances (HB or HB-2-4N + ) solution was added to the 96-well plate and incubated for 2 h. Then 0.1 W cm -2 The cells were irradiated with a 532 nm laser at a power of 10 min. Then, the prepared MTT aqueous solution (20 μL, 5 mg mL -1 After 4 hours of incubation, the solution was removed to dissolve the purple crystals formed by MTT and intracellular succinase. The absorbance at 570 nm in the 96-well plate was measured using a microplate reader. A concentration of 0 μM was used as a reference, and the survival rate was considered to be 100%. Cell survival rates were calculated at different concentrations. Each experiment was repeated 6 times in parallel, and the average value was calculated.
[0226] The half-inhibitory concentration IC of several other cell lines (esophageal cancer cells, bile duct cancer cells, skin squamous cell carcinoma cells) 50 The testing method is basically the same as that for HeLa cells.
[0227] The solvent used for the UV absorption and fluorescence spectra measured in all the examples in this application is N,N-dimethylformamide (DMF).
[0228] As is well known to those skilled in the art, hypocrellin exists in isomers. Therefore, the double bond between positions 13, 14, and 15 in the structure given in the following examples can exist between positions 13 and 14, or between positions 14 and 15, and the two expressions represent the same structure.
[0229] The salts prepared in the following examples all contain anionic counterions. Although the specific ion types are not shown, those skilled in the art can infer the specific anionic types based on the raw materials used to prepare the salts.
[0230] Example 1
[0231] Extraction of Hypocrellin A (HA): HA is extracted from the natural product Hypocrellin. The preparation method is based on the literature reference (Organic Chemistry, 1989, 9, 252-254), and has been appropriately improved. Weigh 100g of Hypocrellin A, pulverize it with a pulverizer, place it in a 2000mL two-necked flask, reflux it for 2h with 1000mL acetone as a solvent, extract 4-5 times until the extract is nearly colorless, remove a small amount of solid insoluble matter that infiltrates in the extract by filtering, then remove acetone by rotary evaporator, dissolve it with 500mL dichloromethane, wash with 4×400mL distilled water, separate the organic layer and spin-dry, wash the solid residue with 5×100mL petroleum ether, and let it dry naturally in air. Then recrystallize it twice with chloroform-petroleum ether. The resulting crystals are the target product Hypocrellin A (HA), with a purity of more than 98%. High-purity hypocrellin A can be further purified by thin-layer silica gel chromatography using petroleum ether:ethyl acetate:anhydrous ethanol (V=30:10:1) as a developing solvent.
[0232] Preparation of Hypocrellin B (HB): HB is obtained by dehydrating HA in an alkaline aqueous solution. The preparation method is based on the literature (Organic Chemistry, 1989, 9, 252-254), with appropriate modifications. The specific method is as follows: 1 g of HA is dissolved in 1000 mL of a 1.5% aqueous KOH solution. After stirring in the dark for 24 hours, the mixture is neutralized with a slight excess of dilute hydrochloric acid and filtered to obtain 0.98 g of hypocrellin B, with a yield of 98%.
[0233] Preparation of deacetylhypocrellin (HC): 200 mg of HB was dissolved in 100 mL of 1.5% potassium hydroxide aqueous solution and refluxed in the dark for 8 h. After cooling, the mixture was neutralized with a slightly excess of dilute hydrochloric acid. The product was extracted with dichloromethane and separated and purified to obtain 110 mg of HC with a yield of 56%.
