Metiamide (SK&F 92058) is a histamine H2-receptor antagonist.

Taltobulin hydrochloride (HTI-286 hydrochloride), a synthetic analogue of the tripeptide hemiasterlin, effectively bypasses P-glycoprotein-mediated resistance both in vitro and in vivo as a robust antimicrotubule agent. It prevents the polymerization of purified tubulin, destabilizes cellular microtubule structures, and triggers both mitotic arrest and apoptosis [1].

Ledipasvir hydrochloride (GS-5885) is a hepatitis C virus NS5A inhibitor, demonstrating potent activity with EC50 values of 34 pM for genotype 1a replicon and 4 pM for genotype 1b replicon. It also functions as a SARS-CoV 3CL pro inhibitor with an IC50 of 1.62 µM [3].

Bivalirudin TFA, a synthetic 20-residue peptide, serves as a reversible inhibitor of thrombin. Its IC50 value highlights its target specificity in vitro, where, combined with Eptifibatide (8 mg/mL) at a low concentration (70 ng/mL), it significantly reduces platelet aggregation induced by thrombin (0.2 U/mL) by approximately 90% [1]. The compound demonstrates no effect on thrombin generation assay (TGA) parameters up to 10 μmol/L [2]. Additionally, it facilitates the binding of MPO to BAEC, leading to functional alterations such as increased NO consumption and enhanced MPO-mediated redox modifications [3]. In vivo studies reveal its efficacy in preventing the rise of antiheparin/PF4 antibody IgG levels in rats, with significant findings from the toxicokinetic assessment signaling its safety profile at tested doses, although higher doses resulted in fatalities [4][5]. In clinical trials, its antithrombotic effects were explored, comparing it with alternatives like Ticagrelor and Clopidogrel in a Phase 4 study.

Acyline TFA, a gonadotropin-releasing hormone (GnRH) peptide analogue, functions as a GnRH antagonist, effectively suppressing gonadotropin and testosterone (T) levels [1].

Canfosfamide (TLK-286, TER286), a glutathione analogue prodrug, becomes activated by glutathione S-transferase P1-1 to induce apoptosis and inhibit DNA-dependent protein kinase's (DNA-PK) catalytic kinase activity. Upon activation, it generates an anticancer alkylating agent and a glutathione derivative, making it useful in researching malignancies [1] [2] [3].

Cyclacillin (Wy-4508), an orally active aminopenicillin antibiotic, demonstrates broad-spectrum antibacterial efficacy against various gram-positive and gram-negative pathogens [1].

Mannose 1-phosphate, an endogenous metabolite, serves as a substrate for the enzyme GDP-mannose pyrophosphorylase to synthesize GDP-Man [1].

Pasireotide diaspartate (SOM230), a long-acting cyclohexapeptide and somatostatin analog, enhances agonist activity across somatostatin receptor subtypes (sst1/2/3/4/5, with pK i values of 8.2, 9.0, 9.1, <7.0, and 9.9, respectively). This compound demonstrates antisecretory, antiproliferative, and proapoptotic activities [1] [2].
