Identification and Characterization of Folliculin-Interacting Protein 
2, FNIP2

    Description of Technology: The invention describes the 
identification and characterization of a FNIP1 homolog, folliculin-
interacting protein 2 (FNIP2), that interacts with folliculin, the 
protein encoded by the FLCN gene, which is responsible for the Birt-
Hogg-Dube' (BHD) syndrome. BHD is a dermatologic disorder associated 
with an increased risk for developing renal cancer, spontaneous 
pneumothorax and lung cysts. FNIP2 binds to the C-terminus of 
folliculin and to AMPK. Importantly, FNIP2 expression was elevated in 
renal tumors seen in BDH patients. This finding suggests that FNIP2 may 
serve as a biomarker for BHD.
    Applications: Research tool; Diagnostic applications.
    Advantages: Could facilitate the development of therapeutic drugs 
to treat the skin lesions and renal tumors that develop in BHD 
patients.
    Development Status: Early stage of development.
    Market: Dermatologic products; Diagnostic applications.

Immunotoxins Made With Modified Cholix Toxin and Uses Thereof

    Description of Technology: Immunotoxins are chimeric molecules 
comprising an antibody targeting moiety and a toxin domain capable of 
killing a cell. Immunotoxins represent an important therapeutic tool 
for the treatment of cancer because they are able to specifically 
target cancer cells while ignoring healthy cells. The major drawback to 
immunotoxins is the development of neutralizing antibodies against the 
toxin portion of the immunotoxin. Many patients treated with 
Pseudomonas exotoxin A (PE) based immunotoxins develop neutralizing 
antibodies after the first administration. As a result, only one 
effective administration of a PE-based immunotoxin is often possible.
    NIH inventors have created a novel immunotoxin, where the toxin 
portion is a truncated Cholera exotoxin (cholix toxin). Although cholix 
toxin retains strong functional and structural similarity to PE, 
neutralizing antibodies to PE do not affect the truncated cholix toxin. 
As a result, cholix toxin-based immunotoxins are of potential utility 
after a patient has developed neutralizing antibodies to PE. The 
ability to deliver two rounds of immunotoxins to a patient will 
increase the successful treatment of various diseases, including 
cancer.
    Application:

[[Page 50828]]

    <bullet> Used as an alternative toxin moiety in immunotoxins.
    <bullet> Immunotoxins can be used for the treatment of various 
cancers, depending on the targeting antibody.
    <bullet> Can be used in tandem immunotoxin therapy with 
immunotoxins having distinct toxin moiety, such as PE-based 
immunotoxins.
    Advantages:
    <bullet> Cholix toxin-based immunotoxins are not affected by 
neutralizing antibodies to by PE-based immunotoxins, permitting 
multiple rounds of immunotoxin therapy.
    <bullet> Ability to target specific cells by choosing specific 
targeting antibodies.

Large Semi-Synthetic Human Antibody Domain Fragment Library

    Description of Technology: Human monoclonal antibodies are 
important for the development of inhibitors, vaccines, diagnostic and 
research tools. Previously a large non-immune human antibody library 
(15 billion (15 x 10\9\) clones) was constructed from the lymph nodes, 
spleen and peripheral blood lymphocytes of 50 donors. One antibody, 
isolated from this library, includes a stop codon in the light chain 
but was still expressed and included a functional heavy chain. The VH 
domain exhibits high levels of expression and high solubility even in 
the absence of a light chain variable domain. This VH domain was used 
as a framework to construct a large human VH domain library (25 billion 
clones) by grafting naturally occurring complementarity determining 
regions (CDRs) from other human antibody libraries and randomly 
mutating one of the CDRs. This library has been used internally for 
selecting anti-HIV antibodies, viruses of biodefense interest and 
cancer-related antigens and is available for licensing as a biological 
material. Several high-affinity binders have already been identified.
    The antibodies generated from this library are small (e.g., about 
more than 14 kDa), highly stable and can be expressed at high levels as 
monomers. The library permits the isolation of antibodies with 
favorable properties: affinity, stability, solubility, high levels of 
expression (at low cost), low rejection rates and low toxicity.
    Applications: Antibody discovery; Therapeutics; Diagnostics; 
Research Materials.

Methods of Preventing Tissue Ischemia

    Description of Technology: Nitric oxide (NO) plays an important 
role as a major intrinsic vasodilator, and increases blood flow to 
tissues and organs. Disruption of this process leads to peripheral 
vascular disease, ischemic heart disease, stroke, diabetes, and many 
more significant diseases.
    Researchers at the NIH have discovered that the matrix protein 
thrombospondin-1 blocks the beneficial effects of NO, and prevents it 
from dilating blood vessels and increasing blood flow to organs and 
tissues. Additionally, the inventors discovered that this regulation 
requires interaction with thrombospondin-1's cell receptor CD47. Murine 
studies revealed that, in the presence of NO, genetically altered mice, 
lacking either thrombospondin-1 or CD47, showed dramatically improved 
blood flow and tissue oxygenation. The inventors have also shown in 
both mice and pigs that by targeting thrombospondin-1 and/or CD47, 
blood flow can be dramatically increased to ischemic tissues. The same 
therapeutics also were found to protect tissues from ischemia/
reperfusion injury.
    Available for licensing and commercial development are:
    <bullet> Compositions and methods of treating tissue ischemia and/
or tissue damage due to ischemia, increasing blood vessel diameter, 
blood flow and tissue perfusion in the presence of vascular disease 
including peripheral vascular disease, atherosclerotic vascular disease 
and stroke.
    <bullet> Compositions and methods for decreasing blood flow as in 
the case of cancer through mimicking the effects of thrombospondin-1 
and CD47 on blood vessel diameter and blood flow.
    Applications:
    <bullet> Potential therapeutics for precise regulation of blood 
flow to tissues and organs.
    <bullet> Efficient methods to increase tissue survival under 
conditions of trauma and surgery.
    <bullet> Efficient methods for the treatment of elderly subjects 
using agents that affect thrombospondin-1 and CD47 and thereby affect 
tissue perfusion.
    <bullet> Methods for treatment of ischemia/reperfusion injury as 
associated with transplant surgery.
    Market:
    <bullet> People with ischemic disease are at increased risk of 
heart attack (myocardial infarction), stroke and peripheral vascular 
disease (PVD). Ischemic heart disease attributes to

more deaths, with 24 percent in the U.S., than any other cause.
    <bullet> Cerebral ischemia is the third leading cause of death 
after heart diseases and cancer.
    <bullet> Decreased blood flow underlies a significant number of 
chronic diseases that account for the majority of morbidity and 
mortality for elderly adults in this country.
    <bullet> Cancer patients and traumatic injury victims requiring 
reconstructive surgery.
    <bullet> Burn patients requiring skin transplants.
    <bullet> Organ transplant patients.

Total Synthesis of Northebaine, Normorphine, Noroxymorphone Enantiomers 
and Derivatives via N-Nor Intermediates

    Description of Technology: A new synthetic process has been found 
in which nordihydrocodeinone, an early intermediate in the total 
synthesis of codeine and related compounds, is easily formed into a 
number of N-nor compounds. These N-nor compounds can be used as 
precursors in the formation of narcotics, narcotic antagonists, or 
narcotic agonist-antagonists.
    The manufacture of drugs of this type, such as northebaine or 
normorphine, can now be done without the use of thebaine as starting 
material. The syntheses have fewer steps than previous methods, and 
also have high yields. In addition, very significant simplification of 
existing thebaine based processes for the manufacture of opiates can be 
expected.
    Applications: Potential new methodology for the synthesis of 
intermediates for drugs including naloxone, naltrexone, percodan and 
nalbuphine.
    Market:
    <bullet> More than a quarter of Americans suffer daily pain, a 
condition that costs the U.S. about $60 billion a year in lost 
productivity.
    <bullet> Americans spent about $2.6 billion in over-the-counter 
pain medications and another nearly $14 billion on outpatient 
analgesics in 2004.
    <bullet> Worldwide, nearly 300 million people are believed to 
suffer from chronic pain.
