Halofuginone (RU-19110), the competitive inhibitor of prolyl-tRNA synthetase(Ki=18.3 nM), could also down-regulate Smad3 and blocked TGF-β signaling at 10 ng/ml in the mammal.

Collagenase Type I is a proteolytic enzyme that primarily targets collagen and is able to break down peptide bonds in collagen. Collagenase is used as a potential therapeutic option to break up the herniated disc material, thereby reducing compression of nearby nerves. Collagenase may aid in the breakdown and reorganization of excessive scar tissue, potentially improving tissue function and appearance. Collagenase has the potential to treat intervertebral disc herniation, keloid, fat mass, lipoma, as well as Peyronie's disease and palmar fibromatosis.

Collagen, Type I, from bovine achilles tendon is a type I collagen derived from bovine achilles tendon, which is widely found in marine invertebrate tissues. Collagen, Type I, from bovine achilles tendon is the only component of collagen fibers that make up the dermis, and plays a major role in bone and connective tissue. connective tissues, and functions primarily by forming and maintaining the integrity of the skeleton.

Forskolin (Coleonol) is a natural product, an adenylate cyclase activator (EC50=0.5 μM). Forskolin increases cAMP levels, activates PXR and FXR, and induces autophagy. Forskolin produces positive inotropic effects in the heart, and has platelet anticoagulant and antihypertensive effects.

(±)-10-Hydroxycamptothecin (Hydroxy Camptothecine) is an alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA topoisomerase, type I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity.

Desaminotyrosine (3-(4-Hydroxyphenyl)propionic acid) is a microbially associated metabolite. Desaminotyrosine protects from influenza through augmentation of type I interferon signaling.

N-Acetyl-L-glutamic acid (Ac-L-Glu-OH) (NAcGlu) is an acetylated amino acid. NAcGlu is biosynthesized from glutamic acid and acetyl-CoA by the enzyme N-acetyl glutamate synthase (NAGS). NAcGlu activates carbamoyl phosphate synthetase in the urea cycle. A deficiency in N-acetyl glutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in the blood leading to the condition called Type I hyperammonemia.

Mycophenolate Mofetil (TM-MMF), an immunosuppressive agent, is the 2-morpholinoethyl ester of mycophenolic acid (MPA), and an inhibitor of inosine monophosphate dehydrogenase (IMPDH).

Sarcosine (Methylglycine) is a competitive inhibitor of the type I glycine transporter (GlyT1) and an N-methyl-D-aspartate receptor (NMDAR) co-agonist.

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.

Actiphenol is a glutarimide antibiotic that exhibits both antifungal and antitumor activity, demonstrating higher potency against pathogens such as coxsackievirus B3, influenza virus A, and herpes simplex virus type 2 than synthetic glutarimide derivatives, and Actiphenol production, along with cycloheximide biosynthesis, is controlled by a single gene cluster encoding an acyltransferase-less type I polyketide synthase in Streptomyces species, highlighting its importance in microbial natural product research.

Altertoxin I (Dihydroalterperylenol) is a quinone-type mycotoxin produced by the fungi Alternaria alternata. It exhibits mutagenic and cytotoxic properties and can mildly disrupt metabolic communication.

cGAMP disodium is a cyclic dinucleotide (CDN) found in bacteria that acts as an endogenous second messenger affecting interferon production in response to cytoplasmic DNA. cGAMP disodium cascades signals from type I interferons and other immune mediators by activating interferon gene stimulator (STING). cGAMP disodium is a potent sublingual immune adjuvant that enables better immune function (serum anti-PA neutralization and airway secretions anti-PA SIgA response).

Glutarylcarnitine (O-glutaroyl-L-carnitine) is a diagnostic metabolite for malonic aciduria and glutaric aciduria type I monitored in most tandem mass spectrometry newborn screening programmes.

Betulinic acid (ALS-357) is a pentacyclic lupane-type triterpene derivative of betulin (isolated from the bark of Betula alba, the common white birch) which has antiretroviral, antimalarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase.

cGAMP (Cyclic GMP-AMPP) diammonium serves as an intrinsic second messenger in metazoans, initiating the production of interferons upon cytosolic DNA detection. It activates the stimulator of interferon genes (STING), subsequently triggering a signaling cascade that culminates in the synthesis of type I interferons and various immune mediators [1] [2] [3] [4].

Ipomoeassin F, a selective and potent inhibitor of endoplasmic reticulum (ER) protein translocation, targets the Sec61 complex's pore-forming subunit (Sec61α) at the ER membrane.
