Description: COMPOSITIONS OF BOSWELLIC ACIDS DERIVED FROM BOSWELLIA SERRATA GUM RESIN, FOR TREATING LYMPHOPROLIFERATIVE AND AUTOIMMUNE CONDITIONS Background of the Invention The present invention concerns new compositions of boswellic acids, methods of using the compositions or mdividual boswellic acids to treat lymphoproliferative and autoimmune conditions, and two new methods of isolating the new compositions. Boswellia serrata (N.O. Burseraceae) is a large, branching, deciduous tree which grows abundantly in the dry, hilly parts of India. It is known as "Dhup", Indian Frankincense or Indian Olibanum. The gum resin exudate of Boswellia serrata, known in the vernacular as "Salai guggal", has been used in the Ayurvedic system of medicine for the management of rheumatism, respiratory diseases, and liver disorders. The major use of Boswellia serrata in contemporary medicine is as an anti-arthritic and anti- inflammatory pharmacological agent. The active principles of the gum resin, boswellic acids, emerge as leading non- steroidal, anti-inflammatory compounds (drugs) NS AID with broad biological activities and low ulcerogemc index. Preciinical studies established that an alcoholic extract of the gum resin displayed marked anti-inflammatory activity in mice and rats, and also inhibited the formation of leukotrienes in rat peritoneal neutrophils in vitro. Boswellic acids decreased the formation of inflammatory leukotπene B4 (B4 is an outcome of the arachidomc acid metabolism) in rat peritoneal neutrophils in a dose-dependent way with IC50 values rangmg from 1.5 to 7uM. The anti-inflammatory mechanism of action of boswellic acids inhibited the leukotπene synthesis via 5-lopoxygenase, but did not affect the 12-lipoxygenase and cyclooxygenase activity. Additionally, boswellic acids did not impair the peroxidation of arachidomc acid by iron and ascorbate. These results suggest that boswellic acids are specific, non-redox inhibitors of leukotriene synthesis either interacting with 5-lipoxygenase or blocking its translocation. Safayhi, H. et al (1992) established and poor art by Ammon et al (EP 0552657) teaches that six boswellic acids are involved in the inhibition of 5-lipoxygenase, thus potentially blocking synthesis of inflammatory leukotπenes and thus useful in treatment of clinical conditions like inflammatory bowel diseases, arthritis, asthma, psoriasis and chronic form of hepatitis. These six compounds listed by Ammon in order of their Diologicai strengtn baseα on IC50-vaιues are as follows: 1. acetyi-11-keto-oeta- boswelhc acid. 2. Beta-Dosweihc acid. 2. 1 1 -keto-oeta-boswelhc acid. 4. Alpha- boswellic aciα. 5. Acetyl-beta-boswelhc aciα ana 6. Acetyi-alpha-boswellic acid. Ammon et al (WO 97/07796) aiso teaches at boswellic acids can be also used as inhibitor of elevated leucocyte eiastase or piasmm activity and useful in clinical conditions cnaracteπzed by tne elevated activity of the eiastase and/or piasmin. The anti-inflammatory properties of the gum resm is attributed to the presence of "boswellic acids". Boswellic acids were found to inhibit two pro-inflammatory enzymes, 5- lipoxygenase (which generates inflammatory leukotπenes) and Human Leukocyte Eiastase (HLE). HLE is a seπne protease which initiates injury to the nssues. which in mm triggers tne lnflamaπon. Studies by Safayhi. H. et al (1997) showed that Acetyl- 1 1-keto-β-bosweilιc acid decreased the activity of human leukocyte eiastase (HLE) in vitro with an IC 50 value of about 15 μM. Prior an by Lee Yue-Wei et al (U.S. Patent No. 5,064,823) aiso teaches that pentacyclic tπterpenoid compounds such as alpha boswellic acid and its acetate, beta boswellic acid and its acetate have an inhibitory effect on topoisomerase I and topoisomerase II which according to authors may result in increased cancer cell differentiation. That process may be considered a cancer treatment modality. An alcoholic extract of the gum resm was examined for anti-carcmo emc properties Dy Mukheπi 5. et al (1970). When tested on mice with Ehrhch ascites carcinoma and S- 180 tumor, the extract inhibited tumor growth and increased the life span of experimental ammais with carcinoma. Summary of the Invention Despite recognized potential of boswellic acids as NSAIDs and as a promising cancer fighting compounds, there are two major obstacles which stand m way of utilization boswellic acids in the health care: (a) pooriy understood relationships between structure/ composition of boswellic acids and their biological utility, and (b) lack of the oosweihc acids proαuct standardized on me basis of cleariy defined structure function ciaim. In the Dresent invention, four Duπfied boswellic acids, individually or in mixtures, were discovered to oe effective in treating lymuπoDroiiferative condinons and autoimmune diseases in animais. including humans. The four puπfied bosweilic acids were shown, in the present invention, in studies to evaluate the effects against macromoiecuiar biosynthesis and cellular growτn of human leukemia HL-60 ceils. The four major pentacyciic mterpenic i boswellic ) acids present in the acidic extract f of Boswellia serrata gum in the present invention are: • β-Boswellic Acid (I) • Acetyl-β-Bosweilic Acid (II) • 1 1 -keto-β-Bosweilic Acid (IE) • Acetyl- 1 1 -keto-β-Boswellic Acid (TV) Figures 1 , 2. and 3 show the inhibitory effects of compounds 1-TV on the DNA. RNA and protein synthesis of HL-60 ceils, respectively (in Fig. 1-3. lines 1, 2, 3 and 4 refer to the data of compounds I, π, HI and IV. respectively). Tables 1 and 2 show the inhibitory effect of a "total organic acids" extract of the exudate of Boswellia serrata on DNA, RNA and protein synthesis or growth in HL-60 cells. Table 3 shows the inhibitory effect of the "total organic acids" extract of the exudate of Boswellia serrata on the incorporation of [ 3 H]thymidine into the DNA of HL-60 cells. The initial rates of incorporation of [ 3 H]-thyπ_idine, [ 3 H]-uridine and [ 3 H]- leucine into trichloroaceric acid (TCA)-insoluble material were utilized to estimate the rates of DNA. RNA. and protein synthesis, respectively, in HL-60 cells. All of the inhibitory effects of compounds I-IV and the alcoholic extract on DNA. RNA and protein synthesis of HL-60 cells were m a dose-dependent manner. Compounds I, II, III and IV exhibited 50% inhibitory activity on the incorporation of [3H]- thymidine into DNA at concentrations of 3.7, 1.4. 0.9 and 0.6 μM. respectively, the mcorporanon of [3H]-uπdine at concentrations of 7.1. 2.3. 2.2 and 0.5 μM. respectively, and the incorporation of [3H]-leucιne into protein at concentrations of 6.3. 5.4, 5.1 and 4.1 μM. respectively, in cultured HL-60 cells incubated for 2 hours. Comparison of the IC50 vaiues indicated that the order of inhibitory activity for compounds I-IV is IV>III>II>I. This observation is a pπncipie behind the new composition of boswellic acids effective in lymphoproliferative and autoimmune disorders. The discovered relationship between structure and activity of specific boswellic acids in inhibition of DNA. RNA and protein synthesis has not been previously repoπed. Our research has determined for the first time that (1) 11-keto group of boswellic acids is a principal moiety for the above described biological activity, and (2) 3-0-acetyi group amplifies that activity further resulting in a predictable cytostatic and lmmunomodulatory effects of boswellic acids. It has been further determined that compound IV. which induced the most pronounced inhibitory effects on DNA. RNA and protein synthesis in HL-60 cells, had an irreversible inhibitory action on DNA synthesis. In this experiment HL-60 cells were preincubated with compound IV at 2 and 8 μM for 30 min at 37°C, washed with phosphate buffer saline and [3H]-thymidine was added to the culture. At desired times, the reacπons were terminated and the rates of DNA synthesis were determined. The results (Fig. 4) showed that the inhibitory effect on DNA synthesis was still dependent upon the concentrations of compound IV and identical to that without washing. This finding suggested that the inhibitory action of compound TV on DNA synthesis was irreversible. The effect of compound IV on cellular growth of HL-60 cells was tested. As shown in Fig. 8, compound IV depressed the growth of HL-60 cells in a dose- dependent manner. Addition of compound TV at 1, 4, or 16 μM to HL-60 cells and incubation at 37°C for 4 days inhibited the cellular growth by 54.5, 71.8 or 98.6%. In order to test whether this growth was the result of cell cytotoxicity, the effects of this compound on ceil viability were examined after 4 days incubation using the trvpan blue exclusion method. The ceils viability at concentrations of 0, 1, 4. 16 μM were 97.0. 96.8. 96.5. or 96.7%, respectively. This expeπment showed that compound IV at the concentrations which significantly inhibited cell growth, did not affect cell viability. These results indicated that inhibition of the ceil growth is due to the cytostatic rather then cytotoxic effects. The inhibition of cell proliferation can be explained by its interference with biosynthesis of DNA. RNA and protein all of which are required for ceil proliferation. These results for the first time establish that composition of bosweilic acid enriched with the compound IV can be used as cytostatic and lmmunomodulatory preparation, due to us profound and weil defined effect on mveioid ceil metabolism.

Detailed Descπpπon of the invention Based on our εxpeπmental data on relationship between structure and function of the four boswellic acids of invention, a novei manufacturing and standardization process for bosweihc acids have oeεn developed. The new standardization process resulted m changes in the nomenclature of the boswellic acids preparation. The new nomenclature included the following changes. The phrase "total organic acids" from Boswellia serrata refers to an organic acid fraction of an extract oi Boswellia serrata or Boswellia serrata gum. The "total organic acids" from Boswellia serrata constitute approximately 65-70%. by weight, of the total alcoholic extract oi Boswellia serrata. In the methods of treatment of the present mvenπon. the daily effective dose, for a 70 kg subject to be treated, is 1- 5000 mg "total organic acids" from Boswellia serrata. 2 to 4 times a day. The preferred daily effective dose is 10-500 mg "total organic acids", 2 to 4 times a day. The more preferred daily effective dose is 100-400 mg "total organic acids". 2 to 4 times a day. The most preferred daily effective dose is 200 mg "total organic acids", 3 times a day. For humans or animals of a body weight other than 70 kg, the above doses can be adjusted accordingly based on the body weight or the body surface area based on methods known in the art. The term "pure boswellic acids" indicates the four major boswellic acids in each dosage form. The "pure boswellic acids" can contain two, three or all four of the four major boswellic acids, i.e. β-boswellic acid (I), acetyl-β-boswellic acid (II), 11-keto-β-boswellic acid (TO), and acetyl-11-keto-β-boswellic acid (TV). The "pure boswellic acids" constitute approximately 25% of the "total organic acids". In the methods of treatment of the present invention, the daiiy effective dose, for a 70 kg subject to be treated, is 0.25-1250 mg "pure bosweliic acids", 2 to 4 times a day. The preferred daily effective dose is 2.5-125 mg "pure boswellic acids". 2 to 4 times a day. The more preferred daily effective dose is 25-100 mg "pure boswellic acids", 2 to 4 times a day. The most preferred daiiy effective dose is 50 mg "pure boswellic acids". 3 times a day. For humans or animals of a body weight other than 70 kg, the above doses can be adjusted accordingly based on the body weight or the body surface area based on methods known m the an. The totai organic acids extract from Boswellia serrata can be administered by topical, inhalational. parenterai or orai routes, or by nasal spray or suppositoπes. Similarly, pure boswellic acids, individual boswellic acids, or mixtures thereof, can be administered oy topical, innaiationai. parenterai or orai routes, or DV nasai spray or suppositoπes. Althougn mere are otner components m the Bosweih serrata gum (e.g. aipha and gamma-Bosweihc acids), the four major pentacyciic tπterpenic (bosweiiic acids present in the acidic extract oi Boswellia serrata gum of the invention used for standardization are: • β-Bosweihc Acid (I) • Acetyi-β-Bosweiiic Acid (II) • 1 1 -keto-β-Bosweiiic Acid (D3) • Acety 1- 1 1 -keto-β-Bosweihc Acid (IV) am (TV) Commercial samples of Bosweiiia serrata extracts vary greatly in their contents of boswellic acids, which limits, as previously mentioned, a reliable use of boswellic acids in medicai and veteπnarv' applications. The analytical results for six commercial samples are indicated m Figure 5. Figure 6 and Figure 7. in terms of content of bosweilic acids, their composition, and totai organic acids content respectively. In many commercial sampies. the most active β-Bosweilic acids are available in negligible quantities only. The totai organic acids content m these samples as determined by titration is indicated in Figure 7. The above analyticai results make it evident that (a) there is need for accurately standardized boswellic acid product by the HPLC method, and (b) that the active components m Boswellia serrata extract cannot be accurately predicted based on titπmetπc method analysis. It is equally interesnng to note that while the titrimetπc method gives more than 50% by weight of organic acids, several of the commercially available products contain only negligible amounts of the two key boswellic acids, namely 11- keto- beta- and acetyl- 11- keto- beta- boswellic acids (Figure 6). Method of extraction of boswellic acids By applying a prior art extraction method on a typical sampie oi Boswellia serrata. a composition was obtained contaming the four boswellic acids, compounds I-IV. at concentrations shown below: Component % by weight I. β-Boswellic Acid 10.1 II.
