The present invention relates to improvements in the field of drug delivery. More particularly, the invention relates to a non-invasive and flexible method and carrier for transporting a compound or drug across the blood-brain barrier of an individual. In particular the present invention relates to a carrier for transporting an agent attached thereto across a blood-brain barrier, wherein the carrier is able to cross the blood-brain barrier after attachment to the agent and thereby transport the agent across the blood-brain barrier.

The invention relates to a pharmaceutical composition comprising an apolipoprotein construct, to an apolipoprotein construct, a nucleic acid sequence encoding the apolipoprotein construct, a vector comprising the nucleic acid sequence, a method for producing the apolipoprotein construct, and a method of treatment comprising administering the apolipoprotein construct. The presented data document that the constructs according to the invention are capable of binding lipids, are capable of binding cubilin, which is a strong Apo Al receptor, stronger than native Apo A-I and that the plasma half life of the constructs is at least tripled compared to native Apo A-I. Together these data document that the constructs according to the invention are strong candidates for treatment of cardiovascular diseases.

The invention relates to genetic approaches to supply nucleotide sequences encoding modified forms of the native forms of apolipoprotein A-I (ApoA-I): mature ApoA-I, preproApoA-I and proApoA-I; including native ApoA-I modified to contain ApoA-I agonists, peptides which mimic the activity of ApoA-I; ApoA-I superagonists, peptides which exceed the activity of native ApoA-I; and modified native ApoA-I having one or more amphipathic helices replaced by the nucleotide sequences of one or more ApoA-I agonists; for the treatment of disorders associated with dyslipoproteinemia, including cardiovascular disease, atherosclerosis, restenosis, hyperlipidemia, and other disorders such as septic shock.

The invention concerns compositions and methods for assay or detection of apolipoprotein-B48 in samples. In particular, it concerns a method for differential measurement of apolipoprotein-B48 (“Apo-B48”) and apolipoprotein-B100 (“Apo-B100”) in biological samples. The invention also concerns synthetic products of Apo-B100, the corresponding antibodies, kits containing same, and their uses for detecting, differentially quantifying and/or recording an amount of Apo-B48 and/or Apo-B100 in a sample, or for quantifying and/or recording atherogenic lipoparticles in a sample. The products, materials and kits hereinabove can also be used for differentially modulating the levels of Apo-B48 and/or Apo-B100 or their activity, in vitro or in vivo, and for regulating lipid metabolism in a subject.

The present invention provides peptidomimetics derived from Apolipoprotein A-I, which is useful for beneficially influencing lipid parameters and/or plasma cholesterol levels. The invention also provides pharmaceutical compositions and methods of treatment for elevated levels of plasma cholesterol.

A compound consisting of an oligonucleotide of sequence CAGCAGCAGAGTCTTCATCAT, where the oligonucleotide has a phosphorothioate backbone throughout, the sugar moieties of nucleotides 1-4 and 18-21 bear 2′-O-methoxyethyl modifications, and the remaining nucleotides (nucleotides 5-17) are 2′-deoxynucleotides, and where the cytosines of nucleotides 1, 4 and 19 are 5-methylcytosines. The compound has increased stability in vivo and improved in vitro and in vivo antitumor activity.

The present invention provides methods for modulating SET activity by contacting SET with a binding agent such as an ApoE peptide derivative. In one embodiment of the invention, a pharmaceutical composition capable of modulating SET activity is administered to a patient for the treatment of an inflammatory or neurological condition. In another embodiment of the invention, compounds efficacious for the treatment of inflammatory and neurological conditions are identified by screening for a binding agent capable of competing with or inhibiting the binding of an ApoE derivative to SET.

It has now been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual suffering from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by the tumor cells, thereby delaying the progression of prostatic tumor cells to an androgen-independent state in an individual Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer. In addition, it has also been found that antisense TRPM-2 has beneficial effect for other cancer types. Specifically, antisense TRPM-2 ODN enhances chemosensitivity in human Renal cell cancer, a normally chemoresistant disease with no active chemotherapeutic agent having an objective response rate higher than 10%. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN. Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed.

This invention provides novel peptides that ameliorate one or more symptoms of atherosclerosis. The peptides are highly stable and readily administered via an oral route. In addition, the peptides inhibit osteoporosis. When administered with a statin, the peptides enhance the activity of the statin permitting the statin to be used at significantly lower dosages. In certain embodiments, the peptides range in length from about 10 up to about 30 amino acids, comprise at least one class A amphipathic helix, and protect a phospholipid against oxidation by an oxidizing agent.

The present invention provides antibodies that preferentially bind to an ApoE(1-272) fragment relative to ApoE(1-299). These antibodies serve to reduce the toxicity of this fragment and find use in treatment and prophylaxis of a variety of neurological diseases.

Disclosed is a novel use of an immunoglobulin Fc fragment, and more particularly, a pharmaceutical composition comprising an immunoglobulin Fc fragment as a carrier. The pharmaceutical composition comprising an immunoglobulin Fc fragment as a carrier remarkably extends the serum half-life of a drug while maintaining the in vivo activity of the drug at relatively high levels. Also, when the drug is a polypeptide drug, the pharmaceutical composition has less risk of inducing immune responses compared to a fusion protein of the immunoglobulin Fc fragment and a target protein, and is thus useful for developing long-acting formulations of various polypeptide drugs.

This invention provides novel peptides that ameliorate one or more symptoms of atherosclerosis. The peptides are highly stable and readily administered via an oral route.

This invention also provides a method of tracking a peptide in a mammal. In addition, the peptides inhibit osteoporosis. When administered with a statin, the peptides enhance the activity of the statin permitting the statin to be used at significantly lower dosages and/or cause the statins to be significantly more anti-inflammatory at any given dose.
