Objective: This research aims to optimize the solid lipid nanoparticles by using full factorial design improve delivery of rivastigmine tartrate (RT), which is used for treatment Alzheimer’s disease (AD). Solid (SLNs) are attracting importance drug developers due their performance. The outcome this will lead improvements in release and solubility RT better therapeutic effect. Methods: Four diff...

The structures of two compounds of L-tartaric acid with quinoline, viz. the proton-transfer compound quinolinium hydrogen (2R,3R)-tartrate monohydrate, C9H8N+.C4H5O6-.H2O, (I), and the anhydrous non-proton-transfer adduct with quinaldic acid, bis(quinolinium-2-carboxylate) (2R,3R)-tartaric acid, 2C10H7NO2.C4H6O6, (II), have been determined at 130 K. Compound (I) has a three-dimensional honeycom...

In the title compound, 2C(8)H(20)N(+)·2C(4)H(5)O(6) (-)·C(4)H(6)O(6)·H(2)O, the presence of the two tetra-ethyl-ammonium cations is balanced by two hydrogen l-tartrate anions. Also present in the asymmetric unit are a mol-ecule of l-tartaric acid and a water mol-ecule. The various components are linked by O-H⋯O hydrogen bonds. In the crystal, two-dimensional networks are formed via O-H⋯O hydrog...

Dementia associated with probable Alzheimer's disease (AD) is one of the most common types of dementia. Patients with AD often have cholinergic deficits in association with the disease. The cholinesterase inhibitors donepezil hydrochloride, galantamine hydrobromide, and rivastigmine tartrate are the current mainstays of symptomatic treatment for patients with AD. In clinical trials for all thre...

The title complex, [Co(C(4)H(5)O(6))(2)(H(2)O)(2)]·2H(2)O, contains a Co(II) ion, two single deprotonated tartrate anions, two coordinated water mol-ecules and two lattice water mol-ecules. The coordination geometry of the Co(II) ion is a distorted octa-hedron with two O atoms from two coordinated water mol-ecules occupying cis positions in the equatorial plane and four O atoms from two hydroge...

The title structure, C(12)H(9)N(2) (+)·C(4)H(5)O(6) (-)·3H(2)O, shows that one of the protons of d-tartaric acid has been transferred to 1,10-phenanthroline. The d-hydrogen tartrate anions are joined together in a head-to-tail fashion via a short hydrogen bond with donor-acceptor distance of 2.4554 (12) Å, unsymmetrical O-H distances of 1.01 (4) Å and 1.45 (4) Å, and a 174 (4)° O-H-O bond angle...

1. Sodium tartrate labelled with C was given orally and parenterally to man and rats, and by direct injection into the caecum in rats. From the differences in urinary excretion after oral and parenteral administration intestinal absorption of tartrate was calculated as 18% of the dose in man and 81% in rats. Urinary tartrate was equivalent to 14% of the dose in man and 70% in rats, the differ­ ...

In the title compound, {[Mn(C(4)H(4)O(6))(H(2)O)]·H(2)O}(n), the Mn(2+) ion is connected to three different tartrate anions and a water mol-ecule, resulting in a distorted MnO(6) octa-hedral geometry. There are two tartrate half-anions in the asymmetric unit, both of which are completed by crystallographic twofold rotation symmetry. The tartrate dianions bridge the Mn(2+) ions to form a wave-li...

In the title compound, C(4)H(10)NO(+)·C(4)H(5)O(6) (-)·H(2)O, the morpholine ring adopts a chair conformation. In the crystal, the tartrate anions are linked via O-H⋯O hydrogen bonds, forming chains propagating along [101]. These chains are linked via N-H⋯O and O-H⋯O hydrogen bonds, involving the morpholinium cation and the water molecule, forming a three-dimensional network.
