[4-(Adamantane-1-carboxamido)-3-oxo-1-thia-4-azaspiro[4.4]nonan-2-yl]acetic acid (4a) and [4-(adamantane-1-carboxamido)-8-nonsubstituted/substituted-3-oxo-1-thia-4-azas-piro[4.5]decane-2-yl]acetic acid (4b–g) derivatives were synthesized; their structures were verified by elemental analysis, infrared spectroscopy, 1H nuclear magnetic resonance (NMR), 13C NMR, and mass?spectroscopy data; and their in vitro cytotoxicity activities were investigated against human hepatocellular carcinoma, human prostate adenocarcinoma, and human lung carcinoma cell lines (HepG2, PC-3, and A549, respectively), and a mouse fibroblast cell line (NIH/3T3). All compounds, except?compound 4e, were found as cytotoxic, especially on A549 cells as compared with the other cells (selectivity index = 2.01–11.6). As a further step, the effects of compounds 4a–c on apoptosis induction were tested and the expression of selected apoptosis genes was analyzed. Among the selected compounds, compound 4a induced apoptosis remarkably. Moreover, computational calculations of the binding of compounds 4a–c to the BIR3 domain of the human inhibitor of apoptosis protein revealed ligand–protein interactions at the atomistic level and emphasized the importance of a hydrophobic moiety on the ligands for better binding.

A series of pyrazole derivatives 4, 5, 6, 12, 13, 14 as well as hydrazone derivatives 7, 10, 11 were synthesized starting from adamantane-1-carbohydrazide as the bioactive core. All newly designed adamantane derivates were established by full characterized using different spectroscopic methods. The novel derivatives were investigated for their antitumor activity against three cell line MCF-7, HepG-2 and A549. They displayed good IC50 values ranged between 1.55 to 42.17 μM in comparison to Doxorubicin (IC50 =3.58–8.19 μM). Surprisingly, adamantine derivatives revealed more sensitivity and selectivity to lung cancer cells (A549) with eight compounds (4, 5, 9a, 9b, 9c, 12, 13a and 14c) having IC50 less than or equal ten micromoles. The most promising three adamantane derivatives 9a, 12 and 13a with IC50 values less than 5 μM were selected to study enzymatic assay for isoenzyme hCAIX and hCAXII. Also, pyrazole core 13a and 12 showed higher KI values than hydrazone derivatives 9a with submicromolar between (0.085–0.527 μM), in comparison to Acetazolamide (0.041–0.068 μM). Compound 13a is the most promising derivatives with anti-proliferative (A549) (IC50=1.55 ± 0.08 μM) which showed CAIX/XII inhibitory activity (KI = 0.085 and 0.14 μM), respectively. Finally, molecular docking simulation was performed to determine the binding modes and possible interaction of the adamantane derivatives within the active site of 3IAI and 1JD0 for CAIX / XII respectively with low binding affinity.

Reaction of 1-adamantyl carbohydrazide (1) with various substituted benzaldehydes and acetophenones yielded the corresponding hydrazide-hydrazones with a 1-adamantane carbonyl moiety. The new synthesized compounds were tested for activities against some Gram-negative and Gram-positive bacteria, and the fungus Candida albicans. Compounds 4a, 4b, 5a, and 5c displayed potential antibacterial activity against tested Gram-positive bacteria and C. albicans, while compounds 4e and 5e possessed cytotoxicity against tested human cancer cell lines.

Epilepsy is the most common neurological condition and cause of substantial morbidity and mortality. In the present study, the molecular hybridization tool was adopted to obtain six Schiff bases of isatin and adamantane-1-carbohydrazide (18-23). Then, their anticonvulsant activity was evaluated using pentylenetetrazole- (PTZ-) induced seizure model using phenobarbitone as a positive control. Our findings showed that compounds 18-23 provided significant protection against PTZ-induced seizure, and maximum activities were associated with compound 23. Moreover, all investigated compounds increased the latency of induced convulsion and reduced the duration of epilepsy with compound 23 being the best. Interestingly, most of the synthesized molecules showed reduction in neurological symptoms and severity of the seizure. Molecular docking studies suggest GABA-A receptor as a potential target, and in silico ADME screening revealed that the pharmaceutical properties of compound 23 are within the specified limit. Thus, compound 23 was identified as a promising candidate that warrants further drug discovery processes.

The synthesis and pharmacological evaluation of C1-substituted adamantane hydrazones, their C2-substituted isomers, and C1-substituted adamantane furanoic carboxamides is described. These new adamantane derivatives exhibited an interesting pharmacological profile in terms of trypanocidal activity and selectivity. The most active adduct with the best selectivity in this study was found to be the phenylacetoxy hydrazone 1 b (2-[4-(tricyclo[3.3.1.13,7]dec-1-yl)phenyl]-N′-[(5-nitrofuran-2-yl)methylene]acetohydrazide; EC50=11±0.9 nm, SITb=770).
