Summary for Patent: 9,365,634
Title: | Aprotinin-like polypeptides for delivering agents conjugated thereto to tissues |
Abstract: | Based on our identification of a polypeptide (Angiopep-7) that is efficiently transported to cells such as liver, lung, kidney, spleen, and muscle, the invention provides polypeptides, conjugates including the polypeptides, and methods for treating diseases associated with these cell types. Unlike other aprotinin related polypeptides identified herein (including Angiopep-3, Angiopep-4a Angiopep-4b Angiopep-5, and Angiopep-6) which efficiently cross the blood-brain barrier (BBB), Angiopep-7 is not efficiently transported across the BBB. |

Application Number: | 12/601,803 |
Patent Claims: | 1. A polypeptide comprising an amino acid sequence having the amino acid sequence of Angiopep-7 (SEQ ID NO: 112) wherein said polypeptide is transported to at least one cell
or tissue selected from the group consisting of liver, lung, kidney, spleen, and muscle.
2. The polypeptide of claim 1, wherein said polypeptide consists of the amino acid sequence of Angiopep-7 (SEQ ID NO: 112). 3. A composition comprising the polypeptide of claim 1. 4. The composition of claim 3 comprising a pharmaceutically acceptable carrier. 5. A conjugate comprising: (a) a vector comprising a polypeptide of claim 1; and (b) a therapeutic agent, diagnostic agent, or detectable label, wherein said agent or label is conjugated to said vector. 6. The conjugate of claim 5, wherein said vector consists of a polypeptide consisting of the amino acid sequence of Angiopep-7 (SEQ ID NO:112). 7. The conjugate of claim 5, wherein said vector is conjugated to a therapeutic agent. 8. The conjugate of claim 5, wherein said therapeutic agent is an anticancer agent. 9. The conjugate of claim 8, wherein said anticancer agent is selected from the group consisting of abarelix, aldesleukin, alitertinoin, allopurinol, altretamine, amifostine, anakinra, anastrozole, arsenic trioxide, asparaginase, azacitidine, BCG Live, bexarotene, bleomycin, bortezomib, busulfan, calusterone, capecitabine, carboplatin, carmustine, zoledronic, chlorambucil, cisplatin, cladribine, clofarabine, cyclophosphamide, cytarabine, dacarbazine, dactinomycin, actinomycin D, dalteparin, darbepoetin alfa, dasatinib, daunorubicin, daunomycin, decitabine, denileukin, Denileukin diftitox, dexrazoxane, docetaxel, doxorubicin, dromostanolone propionate, epirubicin, epoetin alfa, erlotinib, estramustine, etoposide, exemestane, fentanyl, filgrastim, floxuridine, fludarabine, fluorouracil, 5-FU, fulvestrant, gefitinib, gemcitabine, goserelin, histrelin, hydroxyurea, idarubicin, ifosfamide, imatinib, Interferon alfa-2b, irinotecan, lapatinib ditosylate, lenalidomide, letrozole, leucovorin, leuprolide, levamisole, lomustine, CCNU, meclorethamine (nitrogen mustard), megestrol, melphalan (L-PAM), mercaptopurine (6-MP), mesna, methotrexate, methoxsalen, mitomycin C, mitotane, mitoxantrone, nandrolone phenpropionate, nelarabine, oprelvekin, oxaliplatin, paclitaxel, palifermin, pamidronate, pegademase, pegaspargase, pegfilgrastim, peginterferon alfa-2b, pemeterxed, pentostatin, pipobroman, plicamycin (mithramycin), porfimer, procarbazine, quinacrine, rasburicase, sargramostim, sorafenib, streptozocin, sunitinib, sunitinib maleate, talc, tamoxifen, temozolomide, teniposide (VM-26), testolactone, thalidomide, thioguanine (6-TG), thiotepa, thiotepa, thiotepa, topotecan, toremifene, tretinoin (ATRA), uracil mustard, valrubicin, vinblastine, vincristine, vinorelbine, vorinostat, zoledronate, and zoledronic acid. 10.
