Ramipril is an angiotensin-converting enzyme (ACE) inhibitor with IC50 of 5 nM.Target: ACERamipril is an angiotensin-converting enzyme (ACE) inhibitor with IC50 of 5 nM [1]. Ramipril enhances the activity of ACE-associated CK2 and the phosphorylation of ACE Ser1270 in cultured endothelial cells, but is unable to activate JNK or stimulate the nuclear accumulation of c-Jun in endothelial cells expressing a S1270A ACE mutant or in ACE-deficient cells. Prolonged Ramipril treatment increases ACE expression in primary cultures of human endothelial cells and in vivo (mouse lung), which can be prevented by pretreatment with the JNK inhibitor SP600125 [2].Chronic in vivo administration of Ramipril to rats at a dosage that has similar hypotensive effects in vitro HUVECs significantly reduces the rate of LPS-induced apoptosis compared to the other ACE inhibitors, which contrasts with the apoptosis effect in vitro [3]. Ramipril inhibits systolic blood pressure (SBP) with IC50 of 1.97 mg/kg in spontaneously hypertensive rats (SHR). When in combination with AT1-receptor blockade by candesartan-cilexetil increases SBP reduction synergistically rather than additively [4].

Pentoxifylline is a competitive nonselective phosphodiesterase inhibitor.Target: PDEPentoxifylline is a competitive nonselective phosphodiesterase inhibitor which raises intracellular cAMP, activates PKA, inhibits TNF and leukotriene synthesis, and reduces inflammation and innate immunity. In addition, pentoxifylline improves red blood cell deformability, reduces blood viscosity and decreases the potential for platelet aggregation and thrombus formation. Pentoxifylline is also an antagonist at adenosine 2 receptors [1]. Pentoxifylline is generally well tolerated. Based on the totality of the available evidence, it is possible that pentoxifylline could have a place in the treatment of IC as a means of improving walking distance and as a complimentary treatment assuming all other essential measures such as lifestyle change, exercise and treatment for secondary prevention have been taken into account [2]. Pentoxifylline reduce AST and ALT levels and may improve liver histological scores in patients with NALFD/NASH, but did not appear to affect cytokines. Large, prospective, and well-designed randomized, controlled studies are needed to address this issue [3].

Fexaramine is a small molecule farnesoid X receptor (FXR) agonist with 100-fold increased affinity relative to natural compounds. IC50 value:Target:in vitro: In vitro treatment of CDCA or fexaramine elevated the SHP transcript level and occupancy on secretin promoter [1]. Fexaramine significantly enhanced osteoblastic differentiation through the upregulation of Runx2 and enhanced extracellular signal-regulated kinase (ERK) and β-catenin signaling [2]. By mimicking this tissue-selective effect, the gut-restricted FXR agonist fexaramine (Fex) robustly induces enteric fibroblast growth factor 15 (FGF15), leading to alterations in BA composition, but does so without activating FXR target genes in the liver [3].

Acitretin(Ro 10-1670) is a second-generation, systemic retinoid that has been used in the treatment of psoriasis.Target: RAR/RXRAcitretin is a second-generation, systemic retinoid that has been approved for the treatment of psoriasis since 1997. It can be considered one of the treatments of choice for pustular and erythrodermic psoriasis. However, the efficacy of acitretin as a monotherapy for plaque psoriasis is less, although it is often used in combination therapy with other systemic psoriasis therapies, especially ultraviolet B or psoralen plus ultraviolet A phototherapy, to increase efficacy. Such combination treatments may potentially minimise toxicity by using lower doses of each of the two agent [1].Thirty-nine male adult Wistar albino rats were divided into 3 groups as two experimental groups and one control group. The first group consisting 14 rats were applied orally standard dose (0.75 mg/kg/day) acitretin and the second group consisting 16 rats were applied high dose (1.5 mg/kg/day) acitretin.Acitretin was given within dimetil sulphoxide (DMSO), which was diluted with saline solution as a ratio of 1/10, in order to increase its solubility. The control group consisting 9 rats were given only saline solution including DMSO for 8 weeks. After 8 weeks of the administration, half of the rats in the first and second groups and the entire control group were sacrificed under deep ether anaesthesia and bilateral orchiectomy was made. The remainingrats were compared with the control group using a similar method at the end of 8 weeks of wash-off period. The orchiectomy materials were histopathologically evaluated under the light microscope for spermatogenesis according to parameters including spermatogenetic activity, spermatogenetic organization, seminiferous tubular diameter, interstitial Leydig cells and fibroblasts. In our study it was concluded that the standard and high doses of acitretin do not have any effect on the spermatogenesis of threats [2].Clinical indications: PsoriasisFDA Approved Date: Toxicity: nausea; headache; itching; red or flaky skin; dry or red eyes; dry mouth; depression; 0cystitis acne or hair loss
