•     Cartalax (cartilage regulatory peptide) is a synthetically produced tripeptide bioregulator that primarily targets cartilage and connective tissues, aiming to promote the repair and regeneration of the cartilage matrix. Below is a detailed introduction to it:

  Amino Acid Sequence and Chemical Structure

  • Amino Acid Sequence: Ala-Glu-Asp (Alanine-Glutamic acid-Aspartic acid), abbreviated as the single-letter sequence AED.
  • Structural Origin: Its sequence shares homology with a specific sequence in the α-1 chain of type XI collagen, which explains its specific targeting effect on connective tissues.

  Physical and Chemical Properties

  • Substance Classification: It belongs to small-molecule linear tripeptide bioregulators.
  • Physicochemical Parameters: Its molecular formula is C₁₂H₁₉N₃O₈, with a molecular weight of approximately 333.29 Da. The theoretical isoelectric point (pI) is approximately 3.5, making it acidic overall.
  • Physicochemical Characteristics: It typically appears as a white powder. Due to its extremely small molecular size (approximately 346 Da) and the presence of two acidic amino acid side chains, it exhibits excellent water solubility. It is highly soluble in water, normal saline, PBS buffer, and DMSO.

  Main Functions and Mechanisms
  Unlike traditional joint supplements that merely provide structural raw materials (such as collagen powder or glucosamine), the core mechanism of Cartalax is to exert active "programming" and regulatory effects at the genetic and cellular levels:

  • Gene-level Regulation and Matrix Synthesis: Cartalax can penetrate the cell membrane and enter the nucleus, directly binding to specific DNA sequences on chromatin. It upregulates the gene expression responsible for synthesizing type II collagen (COL2A1) and aggrecan (ACAN) in chondrocytes, prompting the cells themselves to increase matrix production and thereby repair cartilage structure.
  • Anti-degradation and Anti-inflammatory Effects: It can inhibit the expression of cartilage-degrading enzymes (such as matrix metalloproteinases, MMPs) and downregulate the signal transduction of pro-inflammatory cytokines (such as IL-1β and TNF-α). This alleviates joint inflammation and prevents further cartilage destruction.
  • Anti-aging and Cellular Protection: Studies on cellular aging have found that Cartalax can reduce the levels of cellular senescence markers (such as p16, p21, and p53) while upregulating the expression of the SIRT6 protein, which is associated with longevity and genomic stability. This improves the proliferative capacity of fibroblasts and delays tissue degenerative changes.
  • Activation of Cartilage Differentiation Factors: Research indicates that Cartalax may also upregulate SOX9 (the master transcription factor for chondrocyte differentiation and cartilage formation) and enhance the TGF-β and BMP signaling pathways, creating a favorable anabolic environment for cartilage repair.

      The core principle for storing parenteral lyophilized powder is strict refrigeration and absolutely no freezing. Before reconstitution, it is generally stored in the dark at 2 to 8°C. Once mixed and dissolved with the solvent, it must be used within a very short period.

Before Reconstitution (Original Packaging)

Strict Refrigeration: The vast majority of parenteral lyophilized powders need to be stored in a refrigerator at 2 to 8°C.

Absolutely No Freezing: Freezing will cause irreversible damage to the structure of proteins and peptides.

Protection from Light and Moisture: The product must be kept in its original packaging to avoid direct sunlight and accidental exposure to moisture.

After Reconstitution (Mixed State)

Highly Time-Sensitive: Once the lyophilized powder is dissolved with a sterile solvent, the stability of the drug drops significantly. It usually needs to be administered immediately or within a very short window (e.g., a few hours).

No Prolonged Storage: Under no circumstances should the reconstituted solution be stored in the refrigerator for use the next day. This can easily lead to loss of efficacy or severe bacterial contamination.
