Patents

Patents are legal documents drawn up by inventors and lawyers and granted by various patent offices around the world, to protect the inventors' intellectual property. The short description accompanying each patent in this Patents section is therefore taken from the legal document as is, with minor corrections for Greek symbols and obvious spelling errors. The patents included in this section may be for material products (defensins or defensin-like peptides or nucleic acid sequences, synthetic or natural) or for novel methods of detecting, quantitating, synthesizing, or delivering antimicrobial peptides/nucleic acid sequences in general. The curators' criterion for inclusion in this section is broader for novel methods than for material products, in the hope that these methods may in future be similarly applied to defensins.

Patents in which the defensins or defensin-like material products and methods as above are not novel, such as biomarker sets containing unmodified defensin or defensin-like peptides or oligonucleotides, are excluded from this section. The exception to such exclusions is where the patent provides other novel defensin-related material products or methods in addition to those non-novel of the biomarker set itself. This exclusion is because the reasonable presence of defensin or defensin-like sequences or indeed any other sequences in patented biomarker sets is necessarily attributed to some prior discovery of disease state correlation with such sequences. The curators have observed therefore that the novel discovery in biomarker-related patents is often the method of biomarker array analysis and validation as well as its resultant implications for diagnostics and prognostics. The expert evaluation of such biomarker analysis and validation is well outside the scope of the Defensins Knowledgebase. The reader is respectfully referred to a biomarker database specific to the disease to perform his own assessment of the validity of the biomarker.

Methods not pertaining to the antimicrobial activity of defensins, but where defensins or antimicrobial peptides or small cationic peptides or disulphide-bonded peptides or their respective nucleic acid sequences are suggested in some unambiguous detail to play a useful role in the method, with or without supporting experimental evidence, are included as well in this section. Patents in which natural defensins are up/downregulated in a clearly defined signal transduction pathway as a result of the unrelated patented novel compound or method are also included. And lastly, all patents showing experimental work done with defensins or antimicrobial peptides or small cationic peptides or disulphide-bonded peptides or their respective nucleic acid sequences, where such peptides or nucleic acid sequences are not the experimental controls, are included without exception.

The data in this section have been extracted from the academic version of SciFinder Scholar 2007 and from public Google search - a wide range of defensin-related patents are included.

Patents
Patent No.: WO 069750
Therapeutic composition with nanoscale activation agents.
Applicant: Joyce TH (2005)
The present invention relates to a composition and method for therapeutic treatment of humans and other mammals. The therapeutic composition of the present invention comprises an encapsulation vesicle, an activation agent such as a nanotube associated with the encapsulation vesicle, a bioactive agent, and an optional targeting ligand. The targeting ligand may be attached to either the activation agent or the encapsulation vesicle. The encapsulation vesicle selectively releases the bioactive agent to achieve a targeted application of the therapeutic or diagnostic potential for the bioactive agent, such as to destroy a diseased cell. The activation agent is activated by an endogenous or exogenous activation condition.

Patent No.: WO 068653
Polymorphisms in the defensin genes in determining the risk of cardiovascular diseases including acute myocardial infarction and coronary heart disease.
Applicant: Salonen JT, Pirskanen M, Haarus J, Tuomainen T-P, Yunus F (2005)
The invention provides a method of identifying a subject's susceptibility or predisposition to, or risk of, developing cardiovascular diseases such as myocardial infarction (MI) or coronary heart disease (CHD) by detecting gene polymorphisms and other gene mutations in a defensin gene from a biol. sample of the subject and obtaining information concerning the family and medical history, blood, serum, plasma and urinary analytes of the subject. The invention also provides a multivariate model, a combination or algorithm of variables which best describes the probability of CHD, esp. MI. The invention also relates to a test kit and software for accomplishing the method. The present invention also relates to a variant defensin gene. Methods of treatment of cardiovascular disease and its ramifications involving restoration of normal defensin levels are discussed.

The present invention provides methods for the isolation and purifn. of defensin polypeptides from white blood cells. More particularly, the present invention provides methods for the extn. and purifn. of human defensin polypeptides, i.e., alpha-defensins 1, 2 and 3, from intact white blood cells, without the need for nitrogen cavitation (Parr bomb) or mech. disruption, centrifugation and gel filtration. The method includes direct extn. by trifluoroacetic acid and acetonitrile followed by cation-exchange chromatog. and hydrophobic chromatog.

Patent No.: WO 034863
Antimalaria proteins derived from chitinase inhibitors, defensins, chitin-binding proteins, and cystein proteinases.
Applicant: Amoah V, Pandolfo A, Batkin T, Richards C (2005)
The present invention includes compounds useful for the control of malaria. One class of compds. includes cysteine proteases that are active against mosquitoes and a second class of compds. includes chimeric proteins having a defensin portion and either a chitinase inhibitor portion or a chitin binding protein portion, wherein the two portions are joined by a linker. Also included in the invention are methods of controlling malaria by application of compds. of the invention to mosquito habitats.
