Model Cell Lines With and Without AKT1 Mutations Derived From Proteus Syndrome Patients
Description of Technology: The Proteus syndrome is a congenital disorder characterized by patchy overgrowth and hyperplasia (cell proliferation) of multiple tissues and organs, along with susceptibility to developing tumors. It is a rare disorder, with incidence of less than one case per million, caused by a somatic mutation. It is also a mosaic disorder, that is one in which cells of the same person have different genetic content from one another. The NHGRI inventors have generated cell lines from patients with Proteus syndrome and discovered that a somatic activating mutation in the serine-threonine kinase AKT1 is associated with Proteus syndrome. AKT1 is an oncogene and an enzyme known to mediate cell proliferation and apoptosis (programmed cell death process) and has been a target for anti-cancer therapies. A number of single-cell lines with the AKT1 mutation showing increased AKT1 phosphorylation and their matched controls without the mutation have been generated. The cell lines can be used to screen therapeutic targets for AKT1, for study design, as models of Proteus syndrome and early stages of cancerous conditions.
Potential Commercial Applications
- Cell lines generated from patients with Proteus syndrome.
- Obtained a number of single-cell lines with the AKT1 mutation and their matched controls without the mutation.
- Cell lines with the mutation showed increased AKT1 phosphorylation for activating mutation.
- Screening of potential therapeutics that target AKT1.
- Cell lines have well-matched controls for rigorous study design.
- Serves as model cell lines of Proteus syndrome and early stages of cancerous conditions.
- In vivo data available (human).

Non-toxic Compounds That Inhibit the Formation and Spreading of Tumors
Description of Technology: Available for licensing are novel pyrrolopyrimidine compounds that disrupt the assembly of the perinucleolar compartment (PNC), a sub-nuclear structure highly prevalent in metastatic tumors. These notable compounds act without overt cytotoxicity.
The presence of the PNC positively correlates with metastatic capacity, making it a potential marker for cancer development and prognosis. These compounds could also serve as useful tools to elucidate the biology driving the formation and maintenance of the PNC, and unravel its association with metastasis.
Potential Commercial Applications
- Use in the therapeutic intervention of metastasis in cancer.
- Use as tools to elucidate the biology of the PNC.
- No existing FDA-approved treatment for the clinical management of metastasis.
- Target is specific to metastatic tumors.
- Compounds are not toxic.
- Broadly acting across all metastatic cancers.
- In vitro data available.

Novel Radio-Labeled Agents for Imaging Alzheimer's Disease-Associated Amyloid
Description of Technology: This technology introduces novel radio-labeled agents for imaging amyloid deposits in the brains of Alzheimer's Disease patients. These are small molecule, radio-ligand compounds that are analogs of benzo[d]thiazole. They are highly specific to amyloid, have low background noise, do not undergo rapid defluoridation and do not produce residual radioactivity in the brain. In addition, the compounds are stable and may be readily synthesized from commercially available starting materials. These compounds may be used in many noninvasive imaging techniques including: magnetic resonance spectroscopy (MRS) or imaging (MRI), or positron emission tomography (PET) or single-photon emission computed tomography (SPECT) to measure amyloid. Non-invasive detection of Alzheimer's disease-associated amyloid plaques in the brain would be valuable for early diagnosis, monitoring, and for clinical development of therapeutic drugs.
Potential Commercial Applications: Imaging agents for use in magnetic resonance spectroscopy (MRS), or imaging (MRI), positron emission tomography (PET) or single-photon emission computed tomography (SPECT).
Competitive Advantages: Highly specificity to amyloid, low background, do not undergo rapid defluoridation and do not produce residual radioactivity in the brain.
Development Stage: Early-stage.

A New Class of Broad-Spectrum Antibiotics: Naturally-Occurring Chrysophaetins and Their Analogues
Description of Technology: This invention, offered for licensing and commercial development, relates to a new class of naturally occurring antimicrobial compounds called Chrysophaetins, and to their synthetic analogues. Isolated from an alga species, the mechanism of action of these compounds is through the inhibition of bacterial cytoskeletal protein FtsZ, an enzyme necessary for the replication of bacteria. FtsZ is responsible for Z-ring assembly in bacteria, which leads to bacterial cell division. Highly conserved among all bacteria, FtsZ is a very attractive antimicrobial target.
The chrysophaetin exhibits antimicrobial activity against drug resistant bacteria, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VRE), as well as other drug susceptible strains. The general structure of the natural compound is shown below:
Potential Commercial Applications
- Therapeutic potential for treating general and drug-resistant bacterial infections in clinical and veterinary populations.
- Antiseptics in hospital settings.
- Effective for commonly occurring drug-resistant infections MRSA and VRE.
- Broad spectrum of efficacy because mechanism of action is against the bacterial protein FtsZ, which has similar structure in all bacteria.
- Potential for additive efficacy when combined with other antibiotics due to distinct mechanism of action.
- Other drugs with similar structure and antibacterial properties can be synthesized using the chemical structure template shown above.
- In vitro data available.
