Compositions and methods for treating obesity, obesity related disorders and for inhibiting the infectivity of human immunodeficiency virus
The present invention relates to methods and pharmaceutical compositions for treating obesity or obesity-related disorders in a subject suffering from or predisposed to developing obesity or an obesity-related disorder, or for inhibiting the infectivity of HIV, by administering oleuropein, an analogue or derivative thereof, or the major metabolites of oleuropein including oleuropein aglycone, hydroxytyrosol, and elenolic acid or their analogues, or derivatives thereof, an iridoid glycoside, or a secoiridoid glycoside or analogues or derivatives thereof, or any combination of the foregoing including olive leave extract. The invention also relates to methods for screening/diagnosing a subject having, or predisposed to having obesity or a related disorder by measuring the expression profiles of an adipogenic gene selected from PPARγ2, LPL and αP2 gene and gene product, or other adipogenic, lipogenic, or lipolytic genes and gene products in an individual. The invention further provides for screening for novel oleuropein analogues.
1. A method for treating a human suffering from obesity consisting essentially of administering to said human a therapeutically effective amount of an olive leaf extract to treat said obesity in the human.
2. The method according to claim 1 wherein the olive leaf extract contains oleuropein.
3. The method according to claim 1 wherein the olive leaf extract is therapeutically effective to modulate adipocyte differentiation in the human.
4. The method according to claim 1 wherein the olive leaf extract is therapeutically effective to modulate adipocyte dedifferentiation and transdifferentiation in the human.
5. The method according to claim 1 wherein the olive leaf extract is therapeutically effective to modulate adipocyte transdifferentiation in the human.
6. The method according to claim 1 wherein the olive leaf extract is therapeutically effective to reduce the number of adipocytes in the human.
7. The method according to claim 1 wherein the human suffering from obesity also suffers from an obesity-related disease selected from the group consisting of diabetes, dyslipidemia, hypertension, cardiovascular disease, and asthma.
8. The method according to claim 1 wherein the olive leaf extract is administered for at least one month.
9. The method according to claim 1 wherein the human suffering from obesity also suffers from one or more diseases selected from the group consisting of metabolic syndrome, type 2 diabetes and human immunodeficiency virus infection.
