Background: A series of phenylurea derivatives were designed and synthesized, The target compounds were subjected to pharmacological studies. Various other parameters such as physicochemical properties, computational studies, and % similarity were also calculated. Materials and Methods: The synthesis of the target compounds has been carried out by reaction of Phenylurea with chloroacetyl chloride to afford 1-(2-chloroacetyl)-3-phenylurea, which further reacted with substituted anilines. All the reactions were monitored by TLC. All the target compounds were purified by recrystallization and characterized by spectroscopic methods. Physicochemical parameters and Log P values of the synthesized derivatives were also calculated. It identified compounds that have the prospect to cross the blood-brain barrier (BBB) and are CNS active. Skeletal muscle relaxant activity was also carried out using the Rotarod method. Results: The data of Log P indicated that the synthesized compounds have the potential to cross the BBB, so they are CNS active. Pharmacological activities of the derivatives showed that the compounds containing chloro group have moderate skeletal muscle relaxant activity. The test compounds possess significant differences between the control group and the treated group. Conclusion: The synthesized derivatives containing chloro group were found to be more potent when compared to standard drug Diazepam. Various others parameters studied revealed that the drug has the potency to cross the blood-brain barrier.

Background: Currently, ringworm treatment drugs include two major categories: first, propylene amine drugs, such as terbinafine, butenafine and naftifine, which exert their bactericidal effects through inhibiting squalene cyclase, causing the lack of ergosterol and accumulation of squalene. The second category of imidazole drugs includes miconazole, econazole, clotrimazole, ketoconazole and bifonazole. Mechanism: These synthetic antifungal agents exhibits their action by inhibiting the lanosterol 14α- demethylation activity of fungal cell, leading to the prevention of the ergosterol synthesis of cell membrane, changing the cell membrane permeability, and resulting in the loss of important intracellular fungal material and causing fungal death. Applications: At present, Imidazole antifungal agents are commonly used drugs in clinical treatment of ringworm with extensive clinical applications. Conclusion: The present review covers the chemistry and detailed pharmacology aspects of luliconazole.

Background: Approach for green chemistry for chemical synthesis is found to be very efficient as it makes the reaction more easily, less tedious, maximize desired products and minimize by-products. Materials & Methods: Utilizing this approach 1, 5-benzodiazepines and its derivatives have been synthesized and evaluated for skeletal muscle and antianxiety activity. 1, 5-benzodiazepine derivatives have attracted great attention due to its diversity of pharmacological activities and its application in heterocyclic synthesis and medicines. The target compounds were synthesized by first reacting o-phenylenediamine with acetophenone to yield 1, 5-benzodiazepines. In the next step the NH of 1, 5-benzodiazepines were chloroacetylated and then the chloro group was substituted with different anilines. The structures were confirmed on the basis of their TLC, IR, 1H NMR and CHN elemental studies. The physicochemical parameters were determined for BBB penetration through online software. Results: The Log P values of the compounds tested showed that compounds have the potential to be CNS active. The compounds were evaluated for the skeletal muscle relaxant activity and antianxiety activity. It was investigated that 1, 5-benzodiazepines derivatives possess significant differences between control group and treated group. Conclusion: Among these derivatives, the compound bearing chloro group possesses the highest skeletal muscle relaxant and antianxiety activity.

BACKGROUND A series of new N-(2-benzoyl-4-chlorophenyl)-2-(4-(substituted phenyl) piperazin-1-yl) acetamides (3a-j) have been synthesized by the chloroacetylation of 2-amino-5- chlorbenzophenone which was further reacted with substituted phenylpiperazine. MATERIAL The chemical structures of the compounds were confirmed on the basis of their TLC, IR, 1HNMR, 13CNMR and by elemental analysis. The physicochemical similarity of the target compounds with respect to standard drug diazepam was assessed by calculating from a set of physicochemical properties using software programs. CONCLUSION Molecular docking studies revealed that the target compounds correctly dock into the binding pocket of the GABAA receptor, while their bioavailability/drug-likeness was predicted to be acceptable but requires future optimization. The anxiolytic and skeletal muscle relaxant activity of the target compounds (3a-j) were evaluated in albino mice. Among them, compound 3h showed potent anxiolytic and skeletal muscle relaxant activity.
