Synthetic phosphodiesterase inhibitor

A specific inhibitor of Bone Morphogenetic Protein (BMP) type 1 receptors ALK2 and ALK3 (IC50  < 0.5 µM). Dorsomorphin analog that exclusively targets the BMP but not VEGF signaling. It is able to inhibit the BMP-induced Smad1/5/8 activation but not the p38/MAP kinase signaling or Activin A-induced Smad2 activation.

MLN 4924 is a selective small molecule that acts as an inhibitor of the Nedd8-activating enzyme. This compound is synthetically derived and functions by inhibiting the conjugation of Nedd8 to cullin proteins. By blocking this pathway, MLN 4924 disrupts the activity of the SCF (Skp, Cullin, F-box containing complex) E3 ubiquitin ligase, leading to an accumulation of proteins that can induce apoptosis and cell cycle arrest. The mode of action of MLN 4924 makes it a critical compound in cancer research as its inhibition of cullin-RING ligase (CRL) ubiquitin ligases places a halt on the degradation of tumor suppressor proteins. This has potential therapeutic implications in oncology, particularly for targeting tumor progression and survival in cancer cells. Studies have shown its efficacy in a variety of malignancies, providing a promising avenue for novel cancer therapies. As an experimental drug, it is primarily utilized within preclinical and early-phase clinical trials to assess its safety and effectiveness in treating different cancer types.

Small molecule antagonist of heparan sulfate that binds to glycosaminoglycans electrostatically. Surfen neutralised anti-coagulant activity of unfractionated and low molecular weight heparins, inhibited enzymatic sulfation and degradation reactions. Surfen also blocked signalling and cell adhesion to fibronectin that was triggered by heparan sulphate.

Kifunensine is a small molecule inhibitor that was designed and synthesized to inhibit plant and animal α-mannosidase I. It is a potent and specific inhibitor with IC50 in nanomolar range. It inhibits the enzyme isoforms in Golgi apparatus (GMI) and endoplasmatic reticulum (ERMI). The compound prevents mannose trimming on glycoproteins and shifts the glycoform content from complex to oligomannose type. Used for the production of recombinant therapeutic glycoproteins with mannose rich N-linked glycans. Kifunensine is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready to use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.

Inhibitor of dioxygenase IDO1

Etoposide is a cytotoxic drug used in cancer chemotherapy. It inhibits DNA replication through inhibition of DNA topoisomerase II, thus catalysing cell cycle arrest and apoptosis.  Etoposide is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready-to-use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.

Inhibitor of guanylyl cyclase

During extraction of lecithin from egg yolk, peptide by-products can be isolated and purified by gel filtration. Within the by-products this has led to the discovery of biologically active value-added products. The egg yolk gel filtration (EFGF) fractions were analysed for their antioxidant and angiotensin converting enzyme (ACE) inhibitory activities. EYGF-56 predominantly contained 3 peptides - SDNRNQGY, IQVPL, and KGLWE. IQVPL in EYGF-56 was found to have minimal antioxidant activity. YPSPV showed some angiotensin converting enzyme (ACE) inhibitory activity.

LRRKtide (also called moesin) is a peptide substrate for leucine-rich repeat kinase 2 (LRRK2). The sequence of LRRKtide has been derived from the ERM proteins: Ezrin (amino acids 561-573), radixin (amino acids 558-570) and moesin (amino acids 539-553). These proteins influence cytoskeletal dynamics by anchoring the cytoskeleton to the plasma membrane. LRRK2 phosphorylates LRRKtide at its Thr558 site.LRRK2 is a large, ubiquitous protein of unknown function. LRRK2 has GTPase and kinase activity, and is located in multiple areas of the cell where it is found associated with intracellular membranes and vesicular structures. Its multiple cellular locations suggest that LRRK2 may be involved in several cellular pathways. LRRK2 is also found in most organs and mutations in LRRK2 have been identified in Parkinson's disease.This peptides has an amidated C-terminal end.

Abiraterone is an anti-cancer drug that has been shown to be effective in treating prostate cancer. It works by blocking the production of testosterone by inhibiting androgen synthesis. Abiraterone does this by inhibiting CYP17A1, which converts cholesterol into pregnenolone, and then into progesterone and testosterone. Furthermore, it binds to the enzyme steroid 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). Abiraterone is usually a last resort for patients who have stopped responding to other lines of hormone therapies, which is known as second-line therapy. Abiraterone is part of our Bio-X ™ Range. These products are aimed at life science researchers who need high quality ready-to-use products for assay development, screening or other R&D work. With a solubility datasheet and convenient vials, all of our Bio-X ™ products are in stock across our global warehouses for rapid delivery and ease of use.

Inhibitor of MEK1/2 kinase enzymes; antineoplastic

1-NM-PP1, also known as 1NM-PP1, is an inhibitor of the Src kinase. Studies have shown that 1-NM-PP1 inhibits analog-sensitive kinases (as-kinases) characterised by a small amino acid as gatekeeper of the ATP binding site. Tested to prevent parasitic infections, 1-NM-PP1 inhibited the Toxoplasma gondii life cycle when used at a higher concentration than 500 nM.

Anti-folate inhibitor of thymidylate synthase

A selective and ATP-competitive inhibitor of mTOR kinase with an IC50 value of 0.8 nM. Inhibits growth of a range of tumor types in vivo and in vitro. Effective in preventing and treating endocrine-resistant breast cancer. Causes autophagy in H838 and A549 cells.

ERKtide Substrate Peptide.

Rosuvastatin is a synthetic lipid-lowering agent, which is a product of pharmaceutical manufacturing derived from extensive research in cardiovascular pharmacology. It functions as an HMG-CoA reductase inhibitor, effectively blocking the enzyme responsible for cholesterol biosynthesis in the liver. By inhibiting this enzyme, Rosuvastatin reduces the production of cholesterol, especially low-density lipoprotein (LDL) cholesterol, which is known to contribute to atherosclerosis. Its primary use is in the management of hypercholesterolemia and related conditions, aimed at reducing cardiovascular morbidity and mortality. Clinical studies have demonstrated its efficacy in not only lowering LDL cholesterol but also in raising high-density lipoprotein (HDL) cholesterol and reducing triglycerides. Furthermore, Rosuvastatin has applications in primary prevention among patients at risk for coronary artery disease, as well as in secondary prevention in those with established cardiovascular disease. Its pharmacokinetic properties, including a long half-life and minimal drug-drug interaction, make it a well-tolerated choice among statins. Continued research is expanding its clinical applications, examining benefits beyond lipid modulation.
