Nonapeptide-1 (Melanostatine™ 5) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

Leupeptin hemisulfate is a protease inhibitor with cell membrane-permeable, reversible, competitive, and oral activities. Leupeptin hemisulfate inhibits the activity of Cathepsin B, Cathepsin H, and Cathepsin L, and blocks fusion of amphipathic lysosomes. Leupeptin hemisulfate also has anti-inflammatory activity.

MEG hemisulfate (Mercaptoethylguanidine hemisulfate) acts as a highly potent and selective suppressor of inducible NO synthase (iNOS), demonstrating EC50 values of 11.5 μM for iNOS, 110 μM for ecNOS, and 60 μM for bNOS in tissue homogenates. It is notably effective as a peroxynitrite scavenger and blocks peroxynitrite-triggered oxidative mechanisms. Furthermore, this compound offers protective benefits across various experimental inflammation prototypes, such as ischemia/reperfusion injury, hemorrhagic shock, periodontitis, inflammatory bowel disease, and both endotoxic and septic shock.

P32/98 hemifumarate is a dipeptidyl peptidase IV (DPP4) inhibitor with hypoglycemic properties that improves insulin sensitivity and β-cell responsiveness in the Zucker diabetic rat model, and may be useful in studies of type 2 diabetes and colitis.

Lipoxamycin hemisulfate (Lipoxamycin) is an inhibitor of serine palmitoyltransferase (IC50 = 21 nM) with antifungal activity.

6α-Methylprednisolone 21-hemisuccinate sodium salt (Asmacortone), a water-soluble ester, is used for allergic, cardiac, and hypoxic emergencies.

Carvedilol phosphate hemihydrate (BM 14190 phosphate hemihydrate) is the phosphate salt form of carvedilol, a racemic mixture and adrenergic blocking agent with antihypertensive activity and no intrinsic sympathomimetic activity.

Phytohemagglutinin (PHA-M) is a lectin, isolated from the red kidney bean , induces apoptosis via increasing proapoptotic protein Bax and activating caspases-3. Anti-tumor activity

Aliskiren hemifumarate (CGP60536B) is an orally active nonpeptide renin inhibitor with antihypertensive activity.

Hematein inhibits Akt/PKB Ser129 phosphorylation, the Wnt/TCF pathway, and increases apoptosis in lung cancer cells. Hematein is an oxidation product of hematoxylin acted as a dye and it also is an allosteric casein kinase II inhibitor (IC50: 0.74 μM).

Paroxetine hydrochloride hemihydrate (Paxil) is an effective and selective serotonin reuptake inhibitor (SSRI).

Hematoxylin (Natural Black 1) is a dye obtained from the heartwood of logwood (Haematoxylon campechianum Linn., Leguminosae) used as a stain in microscopy and in the manufacture of ink.

Atorvastatin hemicalcium salt (Atorvastatin Calcium) is an HMG-CoA reductase inhibitor with oral activity. Atorvastatin hemicalcium salt is used to lower cholesterol.

Hematoporphyrin dihydrochloride (Hematoporphyrin IX dihydrochloride) is a substrate for affinity chromatography of heme-binding proteins.

Potassium guaiacolsulfonate hemihydrate (Potassium guaiacolsulfonate) is an aromatic sulfonic acid used in medicine as an expectorant.

D-Pantothenic acid hemicalcium salt (Calcium pantothenate), a kind of water soluble vitamin, can reduce the patulin content of the apple juice.

Dantrolene depresses excitation-contraction coupling in skeletal muscle by binding to the ryanodine receptor 1 and decreasing intracellular calcium concentration. Ryanodine receptors mediate the release of calcium from the sarcoplasmic reticulum, an essential step in muscle contraction. Dantrolene sodium hemiheptahydrate (Sodium dantrolene) is the sodium salt form of dantrolene, a hydantoin derivative, and direct-acting skeletal muscle relaxant.

Sacubitril hemicalcium salt (AHU377 calcium salt) is a potent NEP inhibitor with an IC50 of 5 nM. Sacubitril hemicalcium salt is a component of the heart failure medicine LCZ696. Sacubitril hemicalcium salt is a prodrug of LBQ657, which is an inhibitor of the zinc metallopeptidase neprilysin. Neprilysin degrades a variety of vasoactive peptides such as atrial and brain natriuretic peptide, bradykinin, adrenomedullin, and endothelin-1. Inhibition of neprilysin leads to an increased level of these peptides and, thus, antihypertensive effects. Formulations containing AHU377 in combination with the angiotensin II receptor antagonist valsartan are used to treat hypertension and heart failure.

3-hydroxycephem is a useful organic compound for research related to life sciences. The catalog number is T4581 and the CAS number is 54639-48-4.

Hydrocortisone hemisuccinate (hydrocortisone 21-hemisuccinate*free acid) is a corticosteroid used as an analytical and chromatography reagent.

Adenine monohydrochloride hemihydrate is a high affinity adenine receptor agonist (Ki = 18 nM at rat adenine receptor). It inhibits forskolin-stimulated cAMP formation in CHO cells transfected with the adenine receptor and also stimulates GTPγS binding (pEC50 values are 8.54 and 7.21 respectively).

Hemin (Hemin chloride) is a chlorinated iron-containing porphyrin, a heme oxygenase (HO)-1 inducer. Hemin has therapeutic activity in porphyrias by reducing heme deficiency in patients, thereby inhibiting δ-aminolevulinic acid synthetase activity through biochemical feedback.

Aminooxyacetic acid hemihydrochloride (Carboxymethoxylamine Hemihydrochloride) is a malate-aspartate shuttle (MAS) inhibitor which also inhibits the GABA degradating enzyme GABA-T.

Quetiapine hemifumarate (ICI-204636), an atypical antipsychotic, is used in the treatment of bipolar I mania, schizophrenia, bipolar II depression, bipolar I depression.
