AR-13324 analog mesylate, an inhibitor of Rho-kinase and the norepinephrine transporter, reduces intraocular pressure in normotensive monkey eyes.

Arecaidine propargyl ester is an agonist of M2muscarinic acetylcholine receptors (mAChRs).1It selectively binds to M2over M1, M3, M4, and M5mAChRs in CHO cells expressing the human receptors (Kis = 0.0871, 1.23, 0.851, 0.977, and 0.933 μM, respectively). Arecaidine propargyl ester induces contractions in isolated guinea pig atrium (pD2= 8.67). It induces apoptosis and the production of reactive oxygen species (ROS) in U87 and U251 glioblastoma cells when used at a concentration of 100 μM.2Arecaidine propargyl ester decreases mean arterial blood pressure in normotensive cats (ED25= 1.9 nmol kg).3It is toxic to house flies (Musca) when administered at a dose of 75 μg fly.4 1.Scapecchi, S., Matucci, R., Bellucci, C., et al.Highly chiral muscarinic ligands: the discovery of (2S,2’R,3’S,5’R)-1-methyl-2-(2-methyl-1,3-oxathiolan-5-yl)pyrrolidine 3-sulfoxide methyl iodide, a potent, functionally selective, M2 partial agonistJ.

15(S)-Latanoprost is an analog of latanoprost in which the hydroxyl at carbon 15 is inverted relative to latanoprost. The IC50 values for the free acid forms of latanoprost and 15(S)-latanoprost were determined to be 3.6 nM and 24 nM, respectively, in a FP receptor binding assay using the cat iris sphincter muscle. A 3 μg dose of 15(S)-latanoprost caused a 1 mmHg reduction of IOP in normotensive cynomolgus monkeys. 15(S)-Latanoprost is a potential impurity in most commercial preparations of the latanoprost bulk drug product.

GAT564 (Compound 15d) is a highly effective allosteric modulator of cannabinoid 1 receptor (CB1R), having EC50 values of 87 nM and 320 nM for cAMP and β-arrestin2, respectively. It significantly enhances the binding of orthosteric ligands to hCB1R. Moreover, GAT564 exhibits remarkable efficacy as a topical agent, resulting in a significant reduction of intraocular pressure (IOP) in an ocular normotensive murine model of glaucoma [1].

Pentoprilat is a member of a series of l-glutarylindoline-2(S)-carboxylic acid derivatives. Pentopril was evaluated as an inhibitor of a cell-free preparation of angiotensin-converting enzyme (ACE) isolated from rabbit lung. Intravenous administration of incremental doses of pentopril to anesthetized normotensive rats produced a dose-related inhibition of angiotensin I (AI) pressor responses. The onset of inhibition of the A1 pressor response was rapid, and substantial inhibition occurred at 5 min after administration of the ACE inhibitors. Pentopril hydrolyzed in vivo to the biologically active free-acid form of CGS 13934. It was well tolerated in normal volunteers and hypertensive patients. Pentopril was developed for the treatment of both hypertension and congestive heart failure. Pentopril produced little clinical improvement and no biochemical improvement in a patients with rheumatoid arthritis.

Quinapril-d5 is intended for use as an internal standard for the quantification of quinapril by GC- or LC-MS. Quinapril is a prodrug form of the angiotensin converting enzyme (ACE) inhibitor quinaprilat. In vivo, quinapril reduces mean arterial pressure in renal hypertensive and spontaneously hypertensive rats. It inhibits angiotensin I-induced pressor responses in normotensive rats and dogs. Quinapril prevents left ventricular heart failure in CHF 14.6 cardiomyopathic hamsters. Formulations containing quinapril have been used in the treatment of hypertension, heart failure, and diabetic nephropathy.

Fosinopril-d7 is intended for use as an internal standard for the quantification of fosinopril by GC- or LC-MS. Fosinopril is a prodrug form of the angiotensin-converting enzyme inhibitor fosinoprilat. Oral administration of fosinopril inhibits angiotensin I-induced pressor responses in normotensive rats, dogs, and monkeys when administered at doses of 15, 15, and 10 µmol kg, respectively. Fosinopril reduces fractional shortening and decreases left ventricular size in a porcine model of congestive heart failure. Formulations containing fosinopril have been used in the treatment of hypertension and congestive heart failure.

BAY-747 (BAY 1165747) 为一种通过口服生效且具有脑渗透性的sGC刺激剂。它能可逆地逆转L-NAME所诱导的记忆障碍并在大鼠中增强认知功能。BAY-747还可在有意识状态下降低正常血压及自发性高血压大鼠(SHR)的血压。此外，BAY-747在mdx mTRG2小鼠模型中改善了与Duchenne肌营养不良症(DMD)相关的骨骼肌功能。

Proadrenomedullin N-terminal 12 peptide (PAMP-12) 是一种内源性肽段，源自人体肾上腺髓质，对应人类PAMP-20的9-20氨基酸，涉及降低血压。它是MAS相关G蛋白偶联受体家族成员X2 (MRGPRX2) 的激动剂。在表达人MRGPRX2的CHO细胞中，PAMP-12抑制forskolin诱导的cAMP积累（EC50 = 57.2 nM），特异性诱导表达MRGPRX2的CHO细胞的钙离子动员（EC50 = 41 nM），而在表达MRGPRX1、MRGPRX3或MRGPRX4的细胞中则无此效应（在1 µM浓度下）。PAMP-12还能作为烟碱型乙酰胆碱受体（nAChRs）的拮抗剂，抑制carbachol诱导的儿茶酚胺释放（IC50 = 1.3 µM）及钙和钠的流入（IC50分别为0.39 µM和0.87 µM），但不抑制组胺诱导的儿茶酚胺释放或钙和钠的流入（IC50 >1 µM），在初级牛肾上腺嗜铬细胞中有此表现。当以10至50 nmol/kg剂量给予正常血压大鼠时，PAMP-12能降低平均动脉血压。

Urocortin II, a neuropeptide hormone within the corticotropin-releasing factor (CRF) family—which comprises mammalian CRF, urocortin I, urocortin III, frog sauvagine, and piscine urotensin I—displays 34, 43, and 37-40% sequence homology with rat and human CRF, human urocortin I, and human urocortin III, respectively. This compound enhances rabbit ventricular myocyte shortening and relaxation in both a time- and concentration-dependent manner. In vivo studies reveal that urocortin II lowers arterial blood pressure in both normotensive and spontaneously hypertensive rats through peripheral CRF2 receptor agonism, inducing dose-dependent tachycardia and hypotension at doses of 3 and 30 pmol/kg. Additionally, it mitigates the visceral pain response to colorectal distension at 10 and 20 μg/kg in conscious rats and delays gastric emptying in mice.

3alpha-Dihydrocadambine exhibits dose-dependent hypotensive and anti-hypertensive effects in anesthetized normotensive rats and in conscious spontaneously hypertensive rats.
