    The present invention relates generally to the fields of organic жидкость and antiproliferative and pro-apoptotic compounds.

    More particularly, the present invention relates to chroman-based compounds and желтая derivatives and their uses as cell proliferation agents proapoptoza agents, immunomodulatory and antiviral agents.

    Biology of cell proliferation and cell death apoptosis is extremely complex comprising numerous intracellular signaling pathways and multiple interacting gene products. In cancer cells may appear multiple defects in the mechanisms of regulation of normal cell proliferation, allowing them жидкость increase in number.

    In addition, cancer cells manifest defects in the mechanisms involved in the elimination of жидкость from the norm cells through multistep process called programmed cell death or apoptosis. Thus, combinations of unregulated cell proliferation and suppression of signaling pathways which induce cell death, cancerous cells provide advantages both in the growth and survival.

    A negative effect on the growth regulatory genes contribute to blocking the cells in the cell cycle. Positive effect on матки growth regulatory genes stimulate the cells to the progression throughout the cell cycle. Genes involved in apoptosis, can be матки pro-apoptotic or antiapopototicheskimi and dynamic balance between them determines whether a cell lives or dies. Cancer cells to желтая and grow in number over time undergo a series of mutation events that remove regulatory control mechanisms that enable them to uncontrollably grow and survive even in the presence proapopototicheskih signals and develop properties that allow them to avoid detection and removal protective immune response system.

    Cancerous tumors can cause death of individuals, if they are not removed surgically or not exposed to effective treatment drugs. There is a wide variety of pathological cell proliferative conditions, in which case to provide therapeutic benefits requires new therapeutic strategies and agents.

    These pathological conditions may occur in almost all cell types capable of abnormal cell proliferation, or deviating from the norms of responsiveness to signals cell death. Among the cell types which exhibit pathological or deviant growth and death characteristics are 1 fibroblasts, 2 vascular endothelial cells and 3 epithelial cells.

    Thus, the need for new ways to treat local and diffuse pathological conditions in all or almost all organ and tissue systems of individuals. Most cancers, whether they are specifically male, such as prostate cancer or testicular cancer, or specifically women, such as breast, ovarian or cervical or affect equally men and women, жидкость as liver cancer, skin or light, exposed over time, enhanced genetic damage and epigenetic events and eventually become vysokometastaticheskimi and difficult to treat.

    Surgical removal of localized cancers has proven effective only when the cancer has not spread beyond the primary lesion. Once the cancer has spread to other tissues and organs, surgical procedures must be supplemented by other, more specific procedures for destruction elimination of the patients or cancer cells. Most commonly used additional procedures for treating diseased or malignant cells such as chemotherapy or radiobiological effects, is not localized on the tumor cells and, although they have a proportionally greater destructive effect on malignant cells, often damaging to some жидкость and normal cells.

    Some derivatives of tocopherols, tocotrienols and vitamin E was used as proapoptotic and DNA synthesis inhibiting agents. Tocopherols differ from tocotrienols in that they have a saturated phytyl side chain rather than an unsaturated isoprenyl side chain. This form of vitamin E induces tumor cell apoptosis without exerting influence apoptosis inducing effects on normal cells. In the prior art, there are no effective means of inhibiting undesirable or uncontrolled желтая proliferation in a wide variety of pathophysiological states, while not affecting or little effect on normal cells.

    The present invention fulfills this longstanding needs and desires in the art. In yet another embodiment, the present invention provides a pharmaceutical composition comprising a compound and a pharmaceutically acceptable carrier is described herein.
