The use of a genetic method to down-regulate RBO/EFR3/EFR3A/EFR3B proteins, TTC7 protein or PI4KIII enzyme protein which interacts with RBO/EFR3/EFR3A/EFR3B proteins and TTC7 protein, or the use of a drug to inhibit PI4KIII protein kinase activity reduces the accumulation of A.sub.42 within neurons and age-dependent synaptic transmission failure and other obstacles in a fruit fly AD model, and obtains an effect of improving the learning and memory abilities of AD model mice. Provided is a method for using an RBO/EFR3/EFR3A/EFR3B inhibitor, a TTC7 inhibitor and a PI4KIII inhibitor to treat Alzheimer's disease. Also provided is a method for screening a drug treating Alzheimer's disease by whether A secretion by nerve cells is promoted or not.

Presently provided are indoximod prodrug and salt compounds and pharmaceutical compositions comprising salts and prodrugs of indoximod, that produce enhanced plasma concentration and exposure to indoximod compared to direct administration of indoximod, in patients in need of treatment of immunosuppression mediated by the indoleamine-2,3-dioxygenase pathway, such as patients with cancer or chronic infectious diseases.

The present invention relates to treating malignancies such as tumors or cancers by orally administering lyophilized compositions comprising arsenic to a subject in such need. Malignancies include various hematological malignancies, such as acute myeloid leukemia (AML) including acute promyelocytic leukemia (APL), myelodysplastic syndrome (MDS), multiple myeloma (MM) and lymphomas and solid tumors including glioblastoma multiforme and breast cancer. Arsenic treatment has shown great promise in the treatment of several cancers but requires daily intravenous (IV) administration. This invention relates to a novel formulation comprising a lyophilized compositions comprising arsenic. As a result, the formulation facilitates a systemic bioavailability comparable to that of intravenous (IV) administration of arsenic trioxide currently practiced. The present invention also relates to a method for lyophilizing the arsenic trioxide, preparing the oral formulation comprising lyophilized compositions comprising arsenic, and a method for treating a subject with malignancies using the oral formulation.

A method for treating a glycoprotein-related disease is disclosed, which comprises: administering a first effective amount of phenol red and a second effective amount of an organic arsenic compound to a subject in need thereof.
