This invention relates to novel andrographolide analogs that are useful for the treatment, prevention and/or amelioration of human diseases of viruses and cancers, the pharmaceutical compositions containing these compounds and the methods for their preparation.
Andrographolide is the main active component of the Herba Andrographitis which is widely used in many countries of Asia for the treatment of viral infections, diabetes, rheumatic arthritis, pharyngolaryngitis and diarrhea (Puri et al., J. Nat. Prod. 1993, 56, 995-999; Zhang and Tan, Clin. Exp. Pharmacol. Physiol. 1996, 23, 675-678; Zhang and Tan, Clin. Exp. Pharmacol. Physiol. 2000, 27, 358-363). Recent report indicated that andrographolide exhibited good cancer therapeutic effects (Satyanarayana et al. Science 2003, 299, 363-370). Significant attention has been paid by several research groups on andrographolide and analogs recent years due to its antitumorogenic and anti-viral activities for treating or preventing pathogenecity of diseases such as AIDS, Alzheimer's disease and hepatitis WO96/17605, U.S. Pat.

To date there has been no report related with structural modification of andrographolide with the introduction of substituents to form andrographolide analogs at both sites of C7 and C15 positions, nor studies of antiviral activity and anticancer activity, nor structure-activity relationship studies of antiviral activity and anticancer activity by the andrographolide analogs modified at both sites of C7 and C15 positions from all literature reviewed.
The purpose of the present invention is to provide a novel andrographolide analogs to their use as antivirus and anticancer agents, to pharmaceutical compositions containing these compounds and to the methods for their preparation, which have the general formula I

Virus Strains:
from NIAID
Methods:
compounds were diluted to 20 mg/mL in DMSO then prepared in for log 10 dilutions of 100 μg/mL down to 0.1 μg/mL) in MEM solution with 50 μg/mL gentamicin and 2% FBS. Each dilution was added to 5 wells of a 96-well plate with 80-100% confluent cells. Three wells of each dilution were infected with virus, and two wells remained uninfected as toxicity controls. The multiplicity of infection (MOI) was as low as possible to achieve CPE within 3-5 days of incubation. A known active compound was tested in parallel as a control. After untreated virus control wells reached maximum cytopathic effect (CPE), each well was scored microscopically. Plates were then stained with neutral red dye for approximately 2 hours, then supernatant dye was removed from the wells and the incorporated dye was extracted in 50:50 Sorensen citrate buffer/ethanol, then the optical density was read on a spectrophotometer. Optical densities were converted to percent of cell controls and normalized to the virus control, then the concentration of test compound required to inhibit CPE by 50% (EC50) was calculated by regression analysis.

Experimental Animals:
Kunming healthy mice provided by the Animal Center of Beijing Academy of Military Medical.
Methods:
xenografts cultured S180 tumor cells were implanted subcutaneously into the flank region of mice and tumors were allowed to grow to the desired average size of 100 mg. The mice were randomized into control and treatment groups with 10 mice per group. The control group was injected with the vehicle used to dissolve the drug. Other groups received the test compounds (example compound 18, 24, 25, 26 and 27) and positive group, cyclophosphamide (CTX) and 5-fluorouracil (5-FU) at the dose and schedule as indicated in Table VI. Injections were I.V. via the tail vein. Tumor measurements were taken every other day 20% tumor growth inhibition which was not statistically significant.
Results: the in vivo experimental data showed anti-tumor efficacy of example compounds 71, 188, 210, 108, 39, 1, 11 and 57 are statistically significant.
