Abstract
Description
[0001] Citation to Related Applications
[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 364,727, filed on May 16, 2022, which is incorporated herein by reference in its entirety. Technical Field
[0003] Provided herein are taxamairin and its analogs for treating inflammatory diseases or conditions (eg, inflammatory bowel disease), as well as a pharmaceutical composition comprising the taxamairin and its analogs, and a method for using and preparing the same. Background Art
[0004] Abnormal inflammatory responses are a major component of a variety of diseases and health conditions. Subjects suffering from inflammatory diseases or conditions often exhibit excess pro-inflammatory cytokines in their body systems, which leads to a host of medical problems.
[0005] One such medical problem is inflammatory bowel disease (IBD), a chronic and progressive immune-mediated inflammatory disease that affects the intestine. In Hong Kong, China, the prevalence of IBD has increased significantly over the past three decades and is on an upward trend. The age-adjusted incidence of IBD has increased significantly, increasing 31-fold from 1985 to 2014. As IBD is an early-onset disease and requires lifelong treatment, the disease has a huge impact on the patient's quality of life and is a burden on the public health system.
[0006] To date, there is no cure for IBD. Therefore, the goal of IBD treatment is to induce and maintain remission without any complications. In Hong Kong, China, the anti-inflammatory drug 5-aminosalicylic acid (5-ASA) remains the most commonly prescribed drug for IBD patients. Since the drug requires multiple doses, long-term patient compliance is low. In addition, more than 25% of IBD patients eventually require surgical intervention within 5 years. Therefore, the discovery and development of new anti-inflammatory drug candidates with high efficacy is imperative.
[0007] Infiltration and activation of intestinal macrophages play an important role in the pathogenesis of IBD. Activated macrophages produce proinflammatory cytokines, such as tumor necrosis factor alpha (TNF-α), IL-1β, IL-6, and nitric oxide (NO), which are able to trigger the activation of NF-κB, MAP kinase, JAK / STAT3, and NLRP3 signaling. Activation of these pathways is known to play an important role in inducing the expression of proinflammatory cytokines, and upregulation of their activity has been demonstrated in patients with IBD. Therefore, strategies targeting the inhibition of proinflammatory signaling pathways and downregulation of cytokines and cytokine-induced inflammatory responses are very important for the development of therapeutic strategies for IBD.
[0008] In view of the above shortcomings, a lot of efforts have been made to discover new drugs and novel mechanisms of action. At the same time, many scientists are interested in the development of natural products, which play a key role in drug discovery due to their huge structural diversity and diverse biological activities with unique mechanisms.
[0009] Icetexane is a series of natural diterpenes isolated from various natural plants. This class of compounds exhibits a series of interesting biological activities and has unique structural characteristics, which have become a hot research topic for biologists and chemists. Icetexane can be divided into different categories according to the presence or absence of oxidation at the C3, C11, C14 and C19 positions ( Figure 1 ).
[0010] Among them, salprzeside represents a highly unsaturated subclass of icetexane. Salprzeside A and B were first isolated and discovered in 1987 from the bark of Taxus mairei, a tree rich in active chemical components, among which taxane diterpenes and corresponding alkaloids are the most well-known, such as the anticancer drug Taxol. The isolation and characterization of salprzeside DH from the young branches of Taxus mairei was first reported in 1998. Brevitaxin was the first terpenoid compound isolated from the bark of Taxus brevifolia in 1995. In 2005, two new salprzesides, namely, unnamed 1 and unnamed 2, were isolated and identified from the dark brown callus culture of Taxus cuspidate. In 2021, two new icetexane diterpenes, Salprzeside A and B, were isolated from Salvia glabra. Extensive studies of derivatives based on the parent core structure have not been conducted. In addition, few biological studies have been conducted on these compounds.
[0011] There is a need to develop drugs based on natural sources and new cellular targets with better safety profiles for the treatment of inflammation. Summary of the invention

[0169] The method for preparing these preparations or compositions comprises the step of combining the compound described herein with a carrier and optionally one or more auxiliary components. Generally, the preparation is prepared by uniformly and closely combining the compound of the present disclosure with a liquid carrier (liquid preparation) (followed by freeze drying (powder preparation for reconstitution using sterile water, etc.) or a finely divided solid carrier or both, and then molding or packaging the product as needed.
[0170] The pharmaceutical composition of the present disclosure suitable for parenteral administration comprises one or more compounds as described herein and one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or can be re-formulated into sterile injection solutions or sterile powders of dispersions before use, and these components can include sugar, alcohol, antioxidants, buffers, antibacterial agents, chelating agents, solutes or suspending agents or thickening agents that make the preparation isotonic with the blood of the intended recipient. In an embodiment, active ingredient and pharmaceutically acceptable carrier are mixed in solution, and then lyophilized to obtain dry powder. The dry powder is packaged as a unit dose form, and can be reconstructed by adding a sterile solution (such as water or saline) to the powder later, so that parenteral administration.
[0171] Examples of suitable aqueous and non-aqueous carriers that can be used in the pharmaceutical compositions of the present invention include water, ethanol, polyols (e.g., glycerol, propylene glycol, and polyethylene glycol, etc.), and suitable mixtures thereof, vegetable oils (e.g., olive oil), and injectable organic esters (e.g., ethyl oleate).

In addition, the extended absorption of injectable pharmaceutical forms can be achieved by including agents that delay absorption (such as aluminum monostearate and gelatin).
[0173] In some cases, in order to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by using a liquid suspension of a poorly water-soluble crystalline or non-crystalline material. The absorption rate of the drug depends on its dissolution rate, which in turn depends on crystal size and crystalline morphology. Alternatively, delayed absorption of a parenteral administration form can be accomplished by dissolving or suspending the drug in an oil vehicle.
[0174] The present disclosure also provides a method for preparing the compounds described herein. The compounds can be easily prepared by many well-known methods known to those of ordinary skill in the art.

[0221] The present disclosure also provides a method of treating inflammatory bowel disease in a subject in need thereof, the method comprising administering a therapeutically effective amount of malathin or a compound described herein.

[0223] In certain embodiments, the method of treating inflammatory bowel disease further comprises the step of co-administering to the subject a therapeutically effective amount of an anti-inflammatory agent.
[0224] The anti-inflammatory agent can be any anti-inflammatory agent known in the art. In certain embodiments, the anti-inflammatory agent is any anti-inflammatory agent that can be used to treat IBD or IBS. Exemplary anti-inflammatory agents include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antibiotics, immunomodulators, and biological drugs, but are not limited to 5-aminosalicylic acid, hydrocortisone, infliximab, and adalimumab.
[0225] The scutellarin described in this article exhibited potent anti-inflammatory activity in lipopolysaccharide (LPS)-induced macrophage and dextran sulfate sodium (DSS)-induced acute colitis mouse models. Scutellarin was able to effectively inhibit LPS-induced nitric oxide production, iNOS expression, and the transcription and secretion of proinflammatory cytokines (including IL-1β, TNF-α, and IL-6). Scutellarin also significantly inhibited inflammatory responses and reduced the susceptibility of mice to DSS-induced colitis. These results provide strong evidence for the anti-inflammatory effects of scutellarin and highlight its potential as a therapeutic agent for the treatment of IBD.
[0226] In addition, the anti-inflammatory activity of scutellarin was evaluated by the inhibitory behavior on the transcription and secretion of pro-inflammatory cytokines (including IL-1β, IL-6 and TNF-α). The results showed that scutellarin could inhibit the secretion of IL-1β, IL-6 and TNF-α in a dose-dependent manner ( Figure 4 A) and the production of pro-inflammatory cytokines at the mRNA level ( Figure 4 B). In addition, taxol was able to significantly reduce the level of iNOS mRNA in LPS-induced macrophages.
[0227] The in vitro inhibitory effect of salvia miltiorrhiza was studied in a mouse model of acute colitis induced by dextran sodium sulfate (DSS), a well-established model that has been widely used for anti-inflammatory and IBD drug development. As shown, 2.5% DSS given to mice via drinking water for 7 days significantly reduced the average body weight of mice, shortened colon length, and increased the levels of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) in colon tissue compared with the control group. Combination treatment with low-dose (50 mg / kg) salvia miltiorrhiza or high-dose (100 mg / kg) salvia miltiorrhiza in DSS-induced mice increased their body weight and food and water consumption ( Figure 5 AC). Compared with the vehicle control, malathionin also reduced the disease activity index (DAI) ( Figure 5 D). Treatment with high and low doses of scutellarin increased colon length by 14.27% and 12.64%, respectively ( Figure 5 EF). Taxol treatment also reduced the levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) while increasing the production of the anti-inflammatory cytokine IL-10 ( Figure 5G). Since chemokines released during inflammation attract leukocytes and lead to a positive feedback loop of cytokine production, inducing further inflammatory responses, we also examined the infiltration of leukocytes into colonic tissues by immunohistochemical (IHC) staining of CD45, a common leukocyte antigen. IHC results showed that the infiltration of CD45-positive cells into colonic tissues was significantly increased, and treatment with taurotaxel or 5-ASA was able to reduce this infiltration ( Figure 5 H). Of note, administration of 200 mg / kg 5-ASA, which is commonly prescribed for IBD patients, did not induce the same degree of improvement as taurotaxel. Histological evaluation of colon sections obtained from DSS-induced mice identified inflammatory cell infiltration, epithelial cell architecture disruption, and crypt loss typical of acute colitis. Figure 5 As shown in Figure 1, treatment with taurotaxel had a beneficial effect on colon histology. Both low-dose and high-dose taurotaxel B treatments were able to reduce DSS-induced damage compared to the vehicle group. Notably, colon sections from mice treated with taurotaxel showed only negligible epithelial damage or crypt loss compared to the vehicle control group or the 5-ASA treatment group, and these results were comparable to those of the uninduced control group. In addition, Alcian blue staining of colon tissues showed that taurotaxel B treatment also reduced damage to goblet cells and maintained mucin secretion ( Figure 5 J).
[0228] In summary, the above results provide solid evidence to support the effective anti-inflammatory activity of taxol and demonstrate its potential for development as a therapeutic agent for inflammatory bowel disease.
[0229] Example
[0230] Example 1 - Representative Procedure for C11 Acylation of Taxolin A (1)
[0231] Taxolin A (1) and B (2) were isolated from natural sources. Compounds 3-8 were prepared by acylation of taxolin A (1).
[0232] To a stirred solution of 0.2 M of the beautiful taxol A (1) in dichloromethane was added the corresponding acid chloride or anhydride (2 equivalents) at 0°C under argon. The resulting solution was warmed to room temperature and stirred until TLC analysis indicated a consumption of 1. The reaction was then terminated by the addition of saturated aqueous sodium bicarbonate and the aqueous phase was extracted with dichloromethane (×3). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated. The crude product was purified by silica gel column chromatography using hexane / ethyl acetate.
[0233] Example 2 - Representative Procedure for Derivatization of Taxol B (2)
[0234] Compounds 9-15 were prepared from taxol B (2). Compounds 9-11 were prepared by demethylation, oxidation or enamine formation. Compounds 12-15 were prepared by 1,2-reduction followed by acylation.

[0236] To a stirred solution of 0.2 M dichloromethane of sedumin B (2) was added BBr3 in acetic acid (2 eq.) at 0°C under argon. The resulting solution was warmed to room temperature and stirred until TLC analysis indicated a consumption of 2. The reaction was worked up according to the above procedure.
[0237] Example 2B - Oxidation of Compound 9
[0238] To a stirred solution of compound 9 in methanol / water (1:1, 0.2 M) was added NaIO4 (3 eq.) at room temperature. The resulting solution was stirred at room temperature until TLC analysis indicated consumption of 9. The reaction was worked up according to the above procedure.

[0242] To a stirred solution of 0.2 M of styracin B (2) in dry THF at -40°C under argon, LiAlH(OBu)3 (3 eq.) was slowly added. The resulting solution was stirred at -40°C until TLC analysis indicated consumption of styracin B (2). The reaction was worked up according to the above procedure.
[0243] Example 3 - Cytotoxicity of Taxusin
[0244] RAW264.7 macrophages were treated with 6.25 μM, 12.5 μM, 25 μM, or 50 μM tauropin for 24 h. The cytotoxicity of tauropin on cells was evaluated using the MTT assay. The results showed that the viability of cells treated with tauropin was not significantly different from that of the control, indicating that tauropin did not exhibit cytotoxicity in macrophages ( Figure 3 A).
[0245] Example 4 - Anti-inflammatory activity of Taxusin
[0246] The anti-inflammatory activity of tausin on nitric oxide production was investigated in LPS-activated RAW264.7 macrophages. The results showed that treatment with tausin significantly reduced LPS-induced nitric oxide production ( Figure 3 B). A dose as low as 12.5 μM of tausin also significantly inhibited the protein expression of iNOS, an upstream regulator of nitric oxide production ( Figure 3 C) Compared with the control, truncatulin at a dose higher than 25 μM significantly inhibited LPS-induced iNOS expression by approximately 90%.
[0247] Example 5 - Inhibition of Nitric Oxide Production
[0248] Inhibition of nitric oxide production by compounds 3-8 at a dose of 12.5 μM (%). In general, acylation of tausin A (1) with the exception of moieties with polar functional groups (e.g., amines or carboxylic acids) resulted in enhanced inhibition of nitric oxide production. In this series, compound 4 showed the best activity in inhibiting nitric oxide production.
[0249]
[0250] Inhibition of nitric oxide production at 12.5 μM (%) = -75. Inhibition of nitric oxide production at 12.5 μM (%) = -28.84.
[0251] Inhibition of nitric oxide production by compounds 9-15 at 12.5 μM (%). Demethylation or oxidation of scutellarin B (2). Enamine formation resulted in a slight decrease in activity. In general, acylation after 1,2-reduction resulted in a significant decrease in activity, with the exception of compound 13, which showed enhanced activity but was highly toxic at higher concentrations.
