walls

Muramic acid is a prevalent constituent found in the cell walls of Gram-positive bacteria, serving as a distinguishing marker for such bacteria[1].

Diosmin (Venosmine) is a bioflavonoid that strengthens vascular walls.

Lignin (Lignine), the primary component of plant cell walls, is a renewable aromatic polymer with strong antioxidant activity. This natural complex biopolymer is both biodegradable and biocompatible.

Xylan, the primary hemicellulose component, is found in the secondary cell walls of flowering plants.

Cefoxitin (Rephoxitin) is a broad-spectrum, orally available second-generation cephalosporins antibiotic. Cefoxitin interferes with the synthesis of bacterial cell walls. Its activity profile includes Gram-negative and Gram-positive bacteria, and is commonly used in abdominal cavity infections, pelvic infections, and certain types of gynecological infections, and is highly effective against anaerobic bacteria.

Chitin is a large, structural polysaccharide found in the cell walls of fungi, the exoskeletons of insects, and certain hard structures in fish and invertebrates.

Diaminopimelic acid or DAPA is a lysine-like amino acid derivative that is a key component of the bacterial cell wall. DAPA is incorporated or integrated into peptidoglycan of gram negative bacteria and is the attachment point for Braun's lipoprotein (BLP or Murein Lipoprotein). BLP is found in gram-negative cell walls and is one of the most abundant membrane proteins. BLP is bound at its C-terminal end (a lysine) by a covalent bond to the peptidoglycan layer (specifically to diaminopimelic acid molecules) and is embedded in the outer membrane by its hydrophobic head (a cysteine with lipids attached). BLP tightly links the two layers and provides structural integrity to the bacterial outer membrane. Diaminopimelic acid can be found in human urine or feces due to the lysis or enzymatic breakdown of gram negative gut microbes.

Ajoene is a disulfide that has been found inA. sativumand has diverse biological activities, including antibacterial, anticancer, antiplatelet, and antioxidant properties.1,2,3,4It is active against Gram-positive (MICs = 5-160 µg/ml) and Gram-negative bacteria (MICs = 136-200 µg/ml), as well as yeasts (MICs = 10-20 µg/ml).1Ajoene is cytotoxic to mouse melanoma cells (IC50= 18 µM), as well as human colon, lung, mammary, and pancreatic cancer cells (IC50s = 7-41 µM).2It reduces tumor growth in a B16/BL6 mouse model of melanoma when administered at a dose of 25 mg/kg every other day and decreases the number of lung metastases when administered prior to tumor cell inoculation at doses ranging from 1-25 mg/kg. It inhibits ADP- or collagen-induced platelet aggregation in isolated baboon platelets when used at concentrations ranging from 75 to 150 µg/ml and in platelet-rich plasma isolated from baboons when administered at a dose of 25 mg/kg.3Ajoene (25 mg/kg) prevents thrombus formation on damaged arterial walls in heparinized pigs in anin situmodel of thrombogenesis.5It also reduces high-fat diet-induced hepatic steatosis, histopathological markers of liver damage, thiobarbituric acid reactive substances (TBARS) formation, and protein oxidation in a mouse model of non-alcoholic fatty liver disease (NAFLD).4 1.Naganawa, R., Iwata, N., Ishikawa, K., et al.Inhibition of microbial growth by ajoene, a sulfur-containing compound derived from garlicAppl.

Cholesteryl palmitic acid is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination of steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides).

HYPOCRELLIN B are photosensitive pigments isolated from Hypocrella bambusae Sacc. Hypocrellin B causes DNA strand breakage, induces apoptosis in ovarian cancer cells, and inhibits proliferation of Staphylococcus by increasing ROS levels, and damaging cell

2 -O-Galloylhyperin (FT-0689359) found in Pyrola. It increases ruminal fiber fermentability by formed wall-bound lignin in primary maize cell walls.

Meso-2,6-diaminopimelic acid is an essential precursor in the biosynthesis of the amino acid L-lysine and a critical component of peptidoglycan in the cell walls of various bacteria.

Arabinoxylan is a primary hemicellulosic polysaccharide found in the cell walls of monocotyledonous grass crops. It consists of a backbone made up of β-(1→4)-linked xylopyranosyl residues.
