P5749 S-(+)-PD 123177 trifluoroacetate salt hydrate ≥98% (HPLC), solid S-(+)-PD 123177 is selective AT2 angiotensin receptor antagonist. The angiotensin AT2 receptor is an atypical seven transmembrane domain receptor that is coupled to activation of tyrosine phosphatase and inhibition of MAP kinase, and does not undergo agonist-induced internalization. An investigation of the occurrence and nature of AT2 receptor phosphorylation revealed that phorbol ester-induced activation of protein kinase C (PKC) in HA-AT2 receptor-expressing COS-7 cells caused rapid and specific phosphorylation of a single residue (Ser354) located in the cytoplasmic tail of the receptor. Agonist activation of AT2 receptors by angiotensin II (Ang II) also caused rapid PKC-dependent phosphorylation of Ser354 that was prevented by the AT2 antagonist, S-(+)-PD 123177, and by inhibitors of PKC. In cells coexpressing AT1 and AT2 receptors, Ang II-induced phosphorylation of the AT2 receptor was reduced by S-(+)-PD 123177 and abolished by treatment with both antagonists or with PKC inhibitors. These findings indicate that the AT2 receptor is rapidly phosphorylated via PKC during homologous activation by Ang II, and also undergoes heterologous PKC-dependent phosphorylation during activation of the AT1 receptor.

T2577 Temozolomide ≥98% (HPLC) Temozolomide is a DNA methylating agent and drug resistance-modifying agent; anti-tumor and anti-angiogenic. Temozolomide induces G2/M arrest and apoptosis through adduction of a methyl group to O6 position of guanine in genomic DNA and functional inactivation of DNA repair protein O(6)-alkylguanine DNA alkyltransferase (AGT) in base excision repair (BER) pathway.
T1633 Theophylline anhydrous, ≥99%, powder Phosphodiesterase inhibitor; diuretic; cardiac stimulant; muscle relaxant; asthma medication.
Theophylline is a tea alkaloid that functions as a nonselective PDE4 inhibitor. It can induce smooth muscle relaxation in the bronchiolae of asthma patients. At increased concentrations, theophylline can function as a reprotoxic agent and can cause infertility by incapacitating Sertoli cells. This subsequently causes the premature release of late differentiating spermatogenic cells.
SML0035 Tiagabine hydrochloride ≥98% (HPLC) Tiagabine hydrochloride is an anticonvulsant and selective GABA reuptake inhibitor through inhibition of the synaptic GABA transporter GAT1.
Tiagabine increases the synaptic GABA and enhances the neuronal inhibition. It is effective as adjunctive treatment of epilepsy and anxiety disorders.
T3202 Torsemide ≥98% (HPLC), solid Torsemide functions in the thick ascending limb of the loop of Henle and enhances the excretion of sodium, chloride and water from the luminal side of the cells. Furthermore, torsemide can treat oedematous conditions that are associated with diseases such as liver cirrhosis, kidney disorders and chronic congestive heart failure2.
Torsemide is a loop diuretic of the pyridine-sulfonylurea class with antialdosteronergic properties and inhibitor of the Na+/K+/2Cl- carrier system.
T6764 Triprolidine hydrochloride ≥99% H1 histamine receptor antagonist.
T104 Tropisetron monohydrochloride solid, ≥98% (HPLC) 3-Tropanylindole-3-carboxylate hydrochloride is a selective 5-HT3 serotonin receptor antagonist.
Tropisetron a selective serotonin 5-HT3 receptor antagonist is used mainly as an antiemetic to treat nausea and vomiting following chemotherapy . In the treatment of fibromyalgia syndrome (FMS) tropisetron reduced not only pain perception but also had a favourable effect on cardiac dysfunction during treatment.
SML0191 Valganciclovir hydrochloride hydrate ≥98% (HPLC) Valganciclovir hydrochloride hydrate is an antiviral used to treat cytomegalovirus infection. It is the prodrug of ganciclovir, a synthetic analog of 2′-deoxy-guanosine which is phosphorylated to a dGTP analog that competitively inhibits the incorporation of dGTP by viral DNA polymerase.
Valganciclovir is a valine ester of Ganciclovir, used to treat cytomegalovirus retinitis in HIV-infected patients. It is rapidly metabolized to ganciclovir by hydrolysis before entering the systemic circulation resulting in improved absorption of the drug.
PZ0004 Varenicline tartrate ≥98% (HPLC) Varenicline tartrate is a partial α4β2 nicotinic receptor agonist and α7 full agonist. Varenicline competitively binds to α4β2 receptors and partially stimulates without creating a full nicotine effect, while simultaneoudly blocking the ability of nicotine to bind to the receptors. Varenicline thus blocks the ability of nicotine to activate α4β2 receptors and stimulate the central nervous mesolimbic dopamine system, believed to be the neuronal mechanism underlying reinforcement and reward experienced upon smoking.
PZ0005 Voriconazole ≥98% (HPLC) Voriconazole is an antifungal used to treat serious fungal infections. Voriconazole inhibits ergosterol synthesis by inhibiting CYP450-dependent 14-α sterol demethylase resulting in a depletion of ergosterol in fungal cell membranes.
Voriconazole is used to treat invasive aspergillosis (IA). It is vigorous against Candida species, including the strains of Candida albicans, which shows resistance to fluconazole.
X2254 XE-991 ≥98% (HPLC) XE-991 is a KCNQ channel blocker; which is more potent than linopiridine (Cat. No. L-134).
Z4152 Zafirlukast ≥98% (HPLC) Zafirlukast is a potent subtype specific cysteinyl leukotriene type 1 receptor (CysLT1) antagonist; antiasthmatic. Zafirlukast has over 1000-fold selectivity for CysLT1, one of two receptors for cysteinyl leukotrienes LTC4, LTD4, and LTE4, which are important mediators of human bronchial asthma.
Zafirlukast plays a key role in alleviating mucus and airway constriction in asthma based inflammatory response. It regulates pancreatic β cells for the secretion of insulin and this functionality is interlinked to the calcium based phosphorylation of the Ca2+/calmodulin-dependent protein kinase II (CaMKII) and protein kinase B (AKT). Zafirlukast has inhibitory potential on ATP-binding cassette (ABC) transporters and reverses the multidrug resistance function of ATP-binding cassette super-family G member 2 (ABCG2). Zafirlukast inhibits mycobacterial nucleoid-associated protein Lsr2 and halts the growth of Mycobacteria.
Z0502 Zaleplon ≥98% (HPLC), solid Zaleplon is a non-benzodiazepine agonist at the benzodiazepine site of the GABAA receptor; sedative; hypnotic.
Z101 Zimelidine dihydrochloride solid Serotonin transport blocker; antidepressant.
Z103 Zolpidem ≥98% (HPLC), solid Potent and selective agonist for the benzodiazepine receptor associated with the GABAA receptor; hypnotic.
SML0076 Zoniporide hydrochloride hydrate ≥98% (HPLC) Zoniporide is a potent and selective inhibitor of Na+/H+ exchanger isoform 1 (NHE-1). IC50 = 59 nM at NHE-1, vs. 12,000 nM at NHE-2; Zoniporide inhibits NHE-1-dependent Na+ update with IC50 of 14 nM.
Zoniporide, a selective inhibitor of sodium-hydrogen exchanger isoform 1 (NHE-1) has cardioprotective effects against myocardial injuries and ischemic insults. It inhibits the swelling human platelets and attenuates cardiac contractile dysfunction in rats. Zoniporide might have neurotoxic effects as it causes peripheral sensory axonopathy.
