The invention discloses a pharmaceutical composition for preventing and / or treating acute pancreatitis. The Anarinone root plays a role in preventing and treating acute pancreatitis by inhibiting oxidative stress (such as improving the activity of superoxide dismutase (SOD) and reducing the content of malondialdehyde (MDA)) and / or inhibiting inflammatory response (such as inhibiting activation of an NF-kappa B signal channel and reducing expression of proinflammatory factors such as IL-6, TNF-alpha and the like); compared with a chemical synthetic medicine octreotide (possibly causing gastrointestinal reaction, abnormal blood glucose and other side effects), the long-term use experience of the Anacarid root serving as a traditional habitual natural medicinal material shows that the Anacarid root possibly has better biocompatibility and lower adverse reaction risk, and a possibly safer treatment choice is provided for patients.

This disclosure provides compositions and methods for treating neuroendocrine tumors. A lipid composition comprising 20 mg of octreotide is administered to a patient once every two weeks. The lipid composition provides slow release of octreotide.

The present invention relates to a mixed green solvent based process for the preparation of peptide. More specifically, the present invention relates to a process of the preparation of Octreotide using greener solvent. The process of present invention also focused on minimizing solvent consumption, especially DMF, trifluoroacetic acid (TFA) and ethers. The process of present invention also substitutes acetonitrile with methanol in the chromatographic purification steps. The process of present invention only addresses environmental concerns associated with DMF usage but also maintains the efficiency and effectiveness of the Octreotide synthesis process.

A formulation of octreotide or pharmaceutically acceptable salts thereof, which provides controlled release of a therapeutically effective amount of octreotide for a period of at least about two months. Methods of treating acromegaly, decreasing growth hormone, decreasing IGP-1, and treating conditions associated with carcinoid tumors and VIPomas by administering a controlled release formulation of octreotide are provided herein.

The invention provides a preparation method of several < 68 > Ga labeled somatostatin receptor (SSTR) probes, and belongs to the technical field of nuclear medicine radiopharmaceuticals. The SSTR targeting compound octreotide is structurally modified by changing types and configurations of amino acids, changing disulfide bonds and increasing non-traditional amino acids on the basis of the existing SSTR targeting compound octreotide, and the series of probes have the advantages of good stability, high targeting property, higher tumor / normal tissue ratio (target / non-target ratio) and the like. The invention not only has a good application prospect in the aspect of PET / SPECT (positron emission tomography / single photon emission computed tomography) imaging agents of high-expression SSTR diseases, but also has potential advantages in the aspect of radioactive therapy of SSTR high-expression tumors.

Methods and devices are described for delivering octreotide to a patient, comprising implanting a controlled release composition for delivering octreotide, wherein the composition does not require hydration prior to implantation, and wherein the composition optionally comprises a release agent.

This invention provides an octreotide-D-configuration oncolytic peptide conjugate, its preparation method, and its applications, belonging to the fields of peptide preparation and biomedical technology. Addressing the shortcomings of L-configuration oncolytic peptides, such as poor stability, low antitumor activity, high cytotoxicity to normal cells, and limitation to intratumoral injection, this invention designs and synthesizes a pH-responsive octreotide-D-configuration oncolytic peptide conjugate. This pH-responsive octreotide-D-configuration oncolytic peptide conjugate significantly improves the antitumor activity and stability of the oncolytic peptide, exhibiting a stronger inhibitory effect on tumor cell proliferation. The conjugate provided by this invention has advantages such as lower toxicity to normal cells and stronger activity against tumor cell lines highly expressing somatostatin receptors. Furthermore, this invention can optimize the administration method of the oncolytic peptide, thus possessing good practical application value.
