Abstract
This review presents the up to date development of fused thiopyranothiazoles that comprise one of the thiazolidine derivatives classes. Thiazolidine and thiazolidinone-related compounds belong to the widely studied heterocycles from a medicinal chemistry perspective. From the chemical point of view, they are perfect heterodienes to undergo hetero-Diels–Alder reaction with a variety of dienophiles, yielding regio- and diastereoselectively thiopyranothiazole scaffolds. The annealing of thiazole and thiopyran cycles in condensed heterosystem is a precondition for the “centers conservative” creation of the ligand-target binding complex and can promote a potential selectivity to biotargets. The review covers possible therapeutic applications of thiopyrano[2,3-d]thiazoles, such as anti-inflammatory, antibacterial, anticancer as well as aniparasitic activities. Thus, thiopyrano[2,3-d]thiazoles may be used as powerful tools in the development of biologically active agents and drug-like molecules.

Abstract
The features of the chemistry of 4-thiazolidinone and pyrazole/pyrazolines as pharmacologically attractive scaffolds were described in a number of reviews in which the main approaches to the synthesis of mentioned heterocycles and their biological activity were analyzed. However, the pyrazole/pyrazoline–thiazolidine-based hybrids as biologically active compounds is poorly discussed in the context of pharmacophore hybrid approach. Therefore, the purpose of this review is to summarize the data about the synthesis and modification of heterocyclic systems with thiazolidine and pyrazoline or pyrazole fragments in molecules as promising objects of modern bioorganic and medicinal chemistry. The description of biological activity was focused on SAR analysis and mechanistic insights of mentioned hybrids. Synthesis and chemistry of pyrazole/pyrazoline–thiazolidine-based hybrids. A diverse spectrum of pyrazole/pyrazoline–thiazolidine-based hybrids biological activities has been presented. Structure activity relationship of pyrazole/pyrazoline–thiazolidine-based hybrids for different activities has been discussed.

Abstract
Effects of a dietary intake of the polyunsaturated omega-6 essential fatty acids (EFAs) linoleic and gamma-linolenic acids (GLA) on blood lipids, platelet function, and vascular prostacyclin production were studied 12 hyperlipidemic patients (doses of 3 g/day) and 12 male Wistar rats (doses of 3 mg/kg/day) for 4 months. In humans, GLA supplementation decreased plasma triglyceride (TG) levels by 48% (p < 0.001) and increased HDL-cholesterol concentration by 22% (p < 0.01). Total cholesterol and LDL-cholesterol levels were significantly decreased by omega-6 EFAs. Platelet aggregation induced by low concentrations of adenosine diphosphate (ADP) and epinephrine, and serum thromboxane B2 decreased by 45% both in humans and animals after GLA supplementation. Bleeding time increased 40% (p , 0.01). In rats, vascular prostacyclin production measured by radioimmunoassay of 6-keto-PGF1 alpha was enhanced by GLA intake. These effects of omega-6 EFAs may contribute to cardiovascular protection and prevention of the atherosclerotic disease.

Abstract
Celiprolol, a new highly cardioselective beta blocker, also has direct vasodilating properties. Since the noninvasive echo Doppler technique applied to the forearm circulation (brachial artery) allows the differentiation of arteriolar vasodilation (revealed by the increasing arterial blood flow velocity) from vasodilation of large arteries (shown by an increase in arterial diameter), it seems important to study the site of celiprolol's vasodilating effect. Thirty-five hypertensive patients, (21 male, 14 female; mean age, 59 +/- 11, range 42-79 years) were treated with increasing doses of celiprolol, 200 and 400 mg, over 15 days. The duplex echo Doppler technique (Aloka 7.5 M Hz probe) was used before and during each celiprolol dose period. Statistical analysis was performed by Student's paired t test. It was observed that celiprolol significantly increases the brachial artery diameter in a dose-dependent manner, and also increases the blood flow velocity (not being direct dose-related). Since the increase in diameter was clear with a higher dose, a dose-dependent increase in blood volume, a decrease in peripheral resistance, and an increase in compliance followed. Since the higher dose of celiprolol did not further reduce blood pressure (BP) in comparison to the lower dose, and a dose-dependent increase in arterial diameter and compliance occurred and a vasodilating effect of celiprolol on arterial wall ensued that was not related to BP. In conclusion, in the doses used, celiprolol dilates both arterioles and large arteries, but the mechanism of action needs to be clarified.

Abstract
We evaluated the effects of piroxicam (n = 20) or fentiazac (n = 11) in 31 hypertensive patients whose blood pressure had been controlled by treatment with propranolol, celiprolol or nifedipine, with or without associated diuretic therapy. No significant change in blood pressure was observed from pretreatment levels during or after a 4 week therapy with these drugs. We conclude that fentiazac and piroxicam do not interfere with an adequate control of high blood pressure in hypertensive patients responding to conventional therapy.
