A composition including a rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof is disclosed. The composition includes an amount and formulation of the rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof sufficient to inhibit one or more of angiogenesis and lymphangiogenesis in an organism and/or sufficient to induce drug-sensitization in or inhibition of a cancer cell in the organism.

The disclosure provides rifamycin and rifamycin derivative compositions, including rifabutin and rifabutin derivative compositions able to cause drug-sensitization in a cancer cell or inhibition of a cancer cell. The disclosure also provides methods of administering such compositions to cancer cells to sensitize them to drugs, such as chemotherapeutics, or directly inhibit them. The disclosure also provides methods of administering such compositions to increase reactive oxygen species (ROS), particularly superoxides, in cancer cells. The disclosure further provides methods of determining whether a cancer will respond to chemotherapeutics and whether to administer rifamycin or a rifamycin derivative based on ROS levels in cancer cells of a patient.
There are presented compounds of the formula
or a pharmaceutically acceptable salt thereof, which are active adenosine A2B receptor antagonists and useful in the treatment of diabetes, diabetic retinopathy, asthma and diarrhea.

Compositions and methods for inhibiting and/or sensitizing or re-sensitizing a parasite to an antiparasitic drug are provided. The compositions can comprise a rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof in an amount and formulation sufficient to inhibit or induce drug-sensitization in a parasite. The methods can comprise administering a rifamycin derivative or a pharmaceutically acceptable salt, hydrate, or prodrug thereof to a parasite in an amount and formulation sufficient to inhibit or induce drug-sensitization in the parasite.

In four or five chemical steps from the 1,2,4-trioxane artemisinin, a new series of 23 trioxane dimers has been prepared. Eleven of these new trioxane dimers cure malaria-infected mice via oral dosing at 3 x 30 mg/kg. The clinically used trioxane drug sodium artesunate prolonged mouse average survival to 7.2 days with this oral dose regimen. In comparison, animals receiving no drug die typically on day 6-7 postinfection. At only 3 x 10 mg/kg oral dosing, seven dimers prolong the lifetime of malaria-infected mice to days 14-17, more than double the chemotherapeutic effect of sodium artesunate. Ten new trioxane dimers at only a single oral dose of 30 mg/kg prolong mouse average survival to days 8.7-13.7, and this effect is comparable to that of the fully synthetic trioxolane drug development candidate OZ277, which is in phase 11 clinical trials.
