Assignee:
Application Number:	15/986,313
Patent Claims:	1. A compound of structural Formula Ia, or a pharmaceutically acceptable salts thereof, and stereoisomers thereof: ##STR00030## wherein: R.sup.1 is selected from the group consisting of (a) C.sub.1-3 alkyl optionally substituted with 1-5 halogens and optionally with one group selected from --OH, --OC.sub.1-3 alkyl optionally substituted with 1-3 halogens, and --CN; (b) --(C.dbd.O)R.sup.4; (c) --CN; (d) --(C.dbd.O)OR.sup.4; (e) --(C.dbd.O)NHR.sup.4; and (f) --(C.dbd.O)NR.sup.5R.sup.6; R.sup.4 is selected from the group consisting of (a) H; and (b) C.sub.1-3 alkyl optionally substituted with 1-5 halogens; R.sup.5 and R.sup.6 are independently selected from the group consisting of C.sub.1-3 alkyl optionally substituted with 1-5 halogens and optionally with one group selected from --OH, and --OC.sub.1-3 alkyl optionally substituted with 1-3 halogens. 2. The compound of Formula Ia as defined in claim 1, or a pharmaceutically acceptable salt thereof, selected from the following compounds: ##STR00031## 3. A pharmaceutical composition comprising a compound of claim 1, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier. 4. A method for improving or treating a disease in a patient in need thereof comprising: administering to said patient an isolated activated antigen presenting cell obtained by treating an isolated antigen presenting cells with an effective amount of a compound of claim 2, or pharmaceutically acceptable salts thereof, and stereoisomers thereof, wherein said isolated antigen-presenting cell is incubated with an antigen specific to a disease before, during or after said treating with said compound, for a time sufficient to obtain said isolated activated antigen-presenting cell, wherein said disease causes expression of said antigen specific to the disease in said patient wherein said dieses is a cancer. 5. The method of claim 4, wherein said isolated antigen presenting cell or said isolated activated antigen presenting cell is a dendritic cell. 6. The method of claim 5, wherein said isolated antigen presenting cell or said isolated activated antigen presenting cell are from the same patient. 7. The method of claim 4, wherein the method further comprises contacting said isolated antigen presenting cells with a maturation cocktail, and wherein said maturation cocktail comprises LPS, MPLA, INF.gamma., CD40L, IL-1.beta., IL-6, TNF-.alpha., PGE-2, or combinations thereof. 8. The method of claim 7, wherein said maturation cocktail is at least one of the following cocktails: a) LPS and INF.gamma.; b) MPLA and INF.gamma.; c) CD40L and INF.gamma.; d) IL-1.beta., IL-6 and TNF-.alpha.; and e) IL-1.beta., IL-6, TNF-.alpha. and PGE-2. 9. The method of claim 4, wherein said cancer is prostate cancer, breast cancer, ovarian cancer, multiple myeloma, brain cancer, glioma, lung cancer, salivary cancer, stomach cancer, thymic epitherlial cancer, thyroid cancer, leukemia, melanoma, lymphoma, gastric cancer, pancreatic cancer, kidney cancer, bladder cancer, colon cancer and liver cancer. 10. A pharmaceutical composition comprising (1) the compound of claim 1 or a pharmaceutically acceptable salt thereof; (2) one or more additional compounds selected from the group consisting of: (a) a cytotoxic agent; (b) an antimetabolite; (c) an alkylating agent; (d) an anthracycline; (e) an antibiotic; (f) an anti-mitotic agent; (g) an hormone therapy; (h) a signal transduction inhibitor; (i) a gene expression modulator; (j) an apoptosis inducer; (k) an angiogenesis inhibitor (l) an immunotherapy agent and (3) a pharmaceutically acceptable carrier. 11. The pharmaceutical composition of claim 10, wherein said cytotoxic agent is taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicin, doxorubicin, daunorubicin, dihydroxy anthracin dione, mitoxantrone, mithramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, puromycin, analogs or homologs thereof, or a combination thereof; wherein said antimetabolites is methotrexate, 6-mercaptopurine, 6-thioguanine, cytarabine, 5-fluorouracil decarbazine, or a combination thereof; wherein said alkylating agent is mechlorethamine, thioepa chlorambucil, melphalan, carmustine (BSNU), lomustine (CCNU), cyclothosphamide, busulfan, dibromomannitol, streptozotocin, mitomycin C, cis-dichlorodiamine platinum (II) (DDP) cisplatin, or a combination thereof; wherein said anthracycline is daunorubicin, doxorubicin, or a combination thereof; wherein said antibiotic is dactinomycin, bleomycin, mithramycin, anthramycin (AMC), or a combination thereof; wherein said anti-mitotic agent is vincristine, vinblastine, or a combination thereof; wherein said signal transduction inhibitor is imatinib, trastuzumab, or a combination thereof; wherein said gene expression modulator is a siRNA, a shRNA, an antisense oligonucleotide, an HDAC inhibitor, or a combination thereof; wherein said immunotherapy agent is a monoclonal antibody, a chimeric antigen receptors (CARs)-T-Cell, or a combination thereof; wherein said hormone therapy is an luteinizing hormone-releasing hormone (LHRH) antagonist; wherein said apoptosis inducers is a recombinant human TNF-related apoptosis-inducing ligand (TRAIL); wherein said angiogenesis inhibitors is sorafenib, sunitinib, pazopanib, everolimus or a combination thereof.
