TAT peptide (TFA) is a cell penetrating peptide (GRKKRRQRRRPQ) derived from the trans-activating transcriptional activator (Tat) from HIV-1[1]. TAT peptide (TFA) (GRKKRRQRRRPQ) functionalized hybrid nanoparticles are also studied due to their combined magnetic enrichment and optical detection for cell separation and rapid cell labelling. A cell viability assay reveals good biocompatibility of these hybrid nanoparticles[2].

NGR peptide Trifluoroacetate containing the asparagine-glycine-arginine (NGR) motif is recognized by CD13/aminopeptidase N (APN) receptor isoforms that are selectively overexpressed in tumor neovasculature.
IC50 Target
CD13/aminopeptidase N (APN) receptor[1]
体外研究 (In Vitro)
NGR peptide can selectively bind to APN/CD13 either immune-captured or expressed on the surface of cells, the receptor of the tumor-homing NGR peptide was suspected to be APN/CD13. The NGR peptide is reported to have the greatest tumor selectivity. An anti-cancer drug Doxorubicin (DOX) coupled to an NGR peptide displays enhanced anti-tumor effects with even lower toxicity than the free drug itself[2].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究 (In Vivo)
NGR peptide imaging in vivo not only provides more insight into NGR’s targeting process, including bio-distribution and pharmacokinetics, but also reveals angiogenic activities related to tumor progression and malignancy[2].

Peptide 401, a potent mast cell degranulating factor from bee venom, suppresses the increased vascular permeability due to intradermal injection of various smooth muscle spasmogens (histamine, and 5-HT).
IC50 Target
serotonin
;
Histamine Receptor
;
体内研究 (In Vivo)
Peptide 401 substantially inhibits the oedema provoked by subplantar injection of carrageenin or intra-articular injection of turpentine in the rat. The ED50 of 401 is c. 0.1 mg/kg. The anti-inflammatory effect is assessed by measurement of the increased 125I-albumin content of an injected site in comparison with an uninjected contralateral site. Peptide 401 also suppresses the increased vascular permeability due to intradermal injection of various smooth muscle spasmogens (histamine, bradykinin, 5-hydroxytryptamine (5-HT), and prostaglandins)[1]. Peptide 401 (MCD peptide) contains 22 residues and occurs in the venom of the common European honey bee to the extent of about 2% by weight . It has powerful anti-inflammatory activity (at doses as low as 0.1 mg/kg) in a variety of animal models, i.e., hind paw oedema in the rat induced by carrageenin or turpentine, adjuvant arthritis in the rat, and increased skin permeability in the rat resulting from subcutaneous injection of bradykinin, prostaglandin E1 kallikrein, histamine and 5- hydroxytryptamine (5-HT). It has a powerful degranulating effect on mast cells and involves the release of histamine and other pharmacologically active agents[2].

CCP peptide is a synthetic cyclic citrullinated peptide (CCP) and used as the substrate for detecting anti-CCP antibodies serologically. CCP peptide functions as a target for autoantibodies with a very high specificity for rheumatoid arthritis (RA)[1][2].
体内研究 (In Vivo)
CCP peptide is used as a new antigenic substrate in anti-CCP ELISA to detect anti-citrullinated protein antibodies (ACPAs). The anti-CCP ELISA is extremely specific (98%), with a reasonable sensitivity (68%). The anti-CCP ELISA is very useful for diagnostic and therapeutic strategies in rheumatoid arthritis (RA)[3].

Transdermal Peptide Disulfide (TD 1 Disulfide(peptide)) is a 11-amino acid peptide, binds toNa+/K+-ATPase beta-subunit (ATP1B1), and mainly interacts with the C-terminus of ATP1B1. Transdermal Peptide Disulfide can enhance the transdermal delivery of many macromolecules[1].
体外研究 (In Vitro)
In the presence of Transdermal Peptide Disulfide, because of the specific binding of Transdermal Peptide Disulfide to ATP1B1, cells will upregulate the level of ATP1B1 to maintain function and structure; as a result, the expression of ATP1B1 increases. However, as time goes on, some Transdermal Peptide Disulfide molecules may be transported into cells by endocytosis; consequently, the expression of ATP1B1 then decreases. The interaction between Transdermal Peptide Disulfide and ATP1B1 changes not only the expression of ATP1B1, but also the localization of ATP1B1 and then the structure of the epidermal layer. This interaction can be attenuated by inhibitors or competitors, which would result in the reduced delivery of macromolecular drugs across the skin[1].
