Differences in the Structure and Antimicrobial Activity of Hydrazones Derived from Methyl 4-Phenylpicolinimidate. MATERIALS 2022; 15:ma15093085.

Abstract
Four novel methyl 4-phenylpicolinoimidate derivatives of hydrazone have been synthesized and evaluated for their antimicrobial activity, including tuberculostatic activity. The compounds obtained are condensates of hydrazonamide or hydrazide with 5-nitro-2-furaldehyde or 5-nitro-2-thiophenecarboxaldehyde. The antimicrobial activity of the tested compounds varied. Compound 3b exhibited significant activity against the tested Gram-positive bacteria (7.8–250 µg/mL). The results of structural tests revealed that the compound is the only one obtained in the form of a Z isomer. Tuberculostatic activity tests showed higher activity of derivatives 3a and 4a containing nitrofuran systems (MICs 3.1–12.5 µg/mL). This research allowed us to identify hydrazone 3b as a starting point for further optimization in the search for antimicrobial drugs. Likewise, compound 4a appears to be a good guiding structure for use in future research on new anti-tuberculosis drugs.

Abstract
Tuberculosis remains one of the most common diseases affecting developing countries due to difficult living conditions, the rapidly increasing resistance of M. tuberculosis strains and the small number of effective anti-tuberculosis drugs. This study concerns the relationship between molecular structure observed in a solid-state by X-ray diffraction and the 15N NMR of a group of pyridine derivatives, from which promising activity against M. tuberculosis was reported earlier. It was found that the compounds exist in two tautomeric forms: neutral and zwitterionic. The latter form forced the molecules to adopt a stable, unique, flat frame due to conjugation and the intramolecular hydrogen bond system. As the compounds exist in a zwitterionic form in the crystal state generally showing higher activity against tuberculosis, it may indicate that this geometry of molecules is the “active” form.

Abstract
Four new picolinohydrazonamide derivatives, namely, 6-methyl-N'-(morpholine-4-carbonothioyl)picolinohydrazonamide, C12H17N5OS, 6-chloro-N'-(morpholine-4-carbonothioyl)picolinohydrazonamide methanol monosolvate, C11H14ClN5OS·CH3OH, 6-chloro-N'-(4-phenylpiperazine-1-carbonothioyl)picolinohydrazonamide, C17H19ClN6S, and 6-chloropicolinohydrazonamide, C6H7ClN4, have been synthesized and characterized by NMR spectroscopy and single-crystal low-temperature X-ray diffraction. In addition, their antibacterial and anti-yeast activities have been determined. The first three compounds adopt the zwitterionic form in the crystal structure regardless of the presence or absence of solvent molecules in the structure. They also adopt the same symmetry, i.e. P21/c (P21/n), unlike the fourth structure which is chiral and has the space group P212121. For all the studied cases, intermolecular N-H...O and N-H...N hydrogen bonds play an essential role in the formation of the structures.

Abstract
Compounds possessing benzimidazole system exhibit significant antituberculous activity. In order to examine how structure modifications affect tuberculostatic activity, a series of benzazole derivatives were synthesized and screened for their antitubercular activity. The compounds 1–20 were obtained by the reaction between o-diamine, o-aminophenol, or o-aminothiophenol with carboxylic acids or thioamides. The newly synthesized compounds were characterized by IR, 1H-NMR, 13C-NMR spectra, and elemental analysis. Synthesized benzazoles were evaluated for their tuberculostatic activity toward Mycobacterium tuberculosis strains. Quantum chemical calculations were performed to study the molecular geometry and the electronic structure of benzimidazoles GK-151B, 4, 6, and benzoxazole 11, using the Gaussian 03W software (Gaussian, Inc., Wallingford, CT, USA). Three-dimensional structure of benzimidazoles 1–3, MC-9, and GK-151B was determined by ab initio calculation using Gamess-US software. The activity of the received benzimidazoles was moderate or good. All of the benzoxazoles and benzothiazoles demonstrated much lower activity. Benzoxazoles were less active by about 50 times, and benzothiazole by 100 times than the benzimidazole analogs. Quantum chemical calculations showed differences in the distribution of electrostatic potential in the benzazole system of benzimidazoles and benzoxazoles. Three-dimensional structure calculations revealed how the parity of the alkyl substituent at the C2 position impacts the activity. Benzimidazole system is essential for the antituberculosis activity that is associated with the presence of the imine nitrogen atom in N-1 position. Its replacement by an oxygen or sulfur atom results in a decrease of the activity. The parity of the alkyl substituent at the C-2 position also modifies the activity.

Abstract
The search for new tuberculostatics is an important issue due to the increasing resistance of Mycobacterium tuberculosis to existing agents and the resulting spread of the pathogen. Heteroaryldithiocarbazic acid derivatives have shown potential tuberculostatic activity and investigations of the structural aspects of these compounds are thus of interest. Three new examples have been synthesized. The structure of methyl 2-[amino(pyridin-3-yl)methylidene]hydrazinecarbodithioate, C8H10N4S2, at 293 K has monoclinic (P21/n) symmetry. It is of interest with respect to antibacterial properties. The structure displays N-H...N and N-H...S hydrogen bonding. The structure of N'-(pyrrolidine-1-carbonothioyl)picolinohydrazonamide, C11H15N5S, at 100 K has monoclinic (P21/n) symmetry and is also of interest with respect to antibacterial properties. The structure displays N-H...S hydrogen bonding. The structure of (Z)-methyl 2-[amino(pyridin-2-yl)methylidene]-1-methylhydrazinecarbodithioate, C9H13N4S2, has triclinic (P-1) symmetry. The structure displays N-H...S hydrogen bonding.

Abstract
The search for new tuberculostatics is important considering the occurrence of drug-resistant strains of Mycobacterium tuberculosis. Three polymorphs of N′-(1,3-dithiolan-2-ylidene)-4-nitrobenzohydrazide (a potentially tuberculostatic agent), C10H9N3O3S2, denoted (I1), (I2) and (I3), and the monohydrate of this compound, C10H9N3O3S2·H2O, (I4), have been characterized by single-crystal X-ray diffraction. The conformations of the molecules in all these structures are very similar. Structures (I1), (I2) and (I3) provide an example of packing polymorphism resulting from different intermolecular interactions.

Abstract
Searches for new tuberculostatic agents are important considering the occurrence of drug-resistant strains of Mycobacterium tuberculosis. The structures of three new potentially tuberculostatic compounds, namely isopropyl methyl (2-hydroxybenzoyl)carbonohydrazonodithioate, C12H16N2O2S2, (Z)-benzyl methyl (2-hydroxybenzoyl)carbonohydrazonodithioate, C16H16N2O2S2, and dibenzyl (2-hydroxybenzoyl)carbonohydrazonodithioate propan-2-ol monosolvate, C22H20N2O2S2·C3H8O, were determined by X-ray diffraction. The mutual orientation of the three main fragments of the compounds, namely an aromatic ring, a dithioester group and a hydrazide group, can influence the biological activity of the compounds. In all three of the structures studied, the C(=O)NH group is in the anti conformation. In addition, the presence of the hydroxy group in the ortho position of the aromatic ring in all three structures leads to the formation of an intramolecular hydrogen bond stabilizing the planarity of the molecules.

Abstract
The emergence of drug-resistant strains ofMycobacterium tuberculosishas intensified efforts to identify new lead tuberculostatics. Our earlier studies concluded that the planarity of a molecule correlates well with its tuberculostatic activity. According to our hypothesis, only derivatives whose molecules are capable of adopting a planar conformation may show tuberculostatic activity. The structures of three new potentially tuberculostatic compounds, namelyN′-[bis(methylsulfanyl)methylidene]-N-methyl-4-nitrobenzohydrazide (denotedG1), C11H13N3O3S2,N′-[bis(benzylsulfanyl)methylidene]-N-methyl-4-nitrobenzohydrazide (denotedG2), C23H21N3O3S2, andN′-[(benzylsulfanyl)(methylsulfanyl)methylidene]-4-nitrobenzohydrazide (denotedG3), C16H15N3O3S2, were determined by X-ray diffraction. The significant distortion from planarity caused by the methyl substituent at the N atom of the hydrazide group or the NO2substituent in the aromatic ring leads to the loss of tuberculostatic activity forG1,G2 andG4 {systematic name:N′-[bis(methylsulfanyl)methylidene]-2-nitrobenzohydrazide}. A similar effect is observed when there are large substituents at the S atoms (G2 andG3).

Abstract
Methyl 2-(3,4-dichlorobenzoyl)-1-methylhydrazinecarbodithioate, C10H10Cl2N2OS2, (F1), butyl 2-(3,4-dichlorobenzoyl)-1-methylhydrazinecarbodithioate, C13H16Cl2N2OS2, (F2), and 3,4-dichloro-N-(2-sulfanylidene-1,3-thiazinan-3-yl)benzamide, C11H10Cl2N2OS2, (F3), were studied by X-ray diffraction to test our hypothesis that planarity of aryloylhydrazinedithiocarbazic acid esters is a prerequisite for tuberculostatic activity. All compounds examined in this study are inactive and nonplanar due to twists along two specific bonds in the central frame of the molecules. The significant twist at the N—N bond, with an C—N—N—C(S) torsion angle of about 85°, results from repulsion caused by a methyl substituent at the N′ atom of the hydrazide group. The other twist is that within the benzoyl group at the C(O)—Ph bond,i.e.the N—C(=O)—C(phenyl)—C torsion angle: the values found in the studied structures (25–30°) are in agreement with those observed in other compounds containing a similar fragment. As some nonplanar benzoyl derivatives are active, it seems that planarity of the hydrazinedithioate fragment is more important for tuberculostatic activity than planarity of the aryloyl group.

Compound (D1) (with two molecules in the asymmetric unit) was the only one showing tuberculostatic activity of the same range as the common drugs isoniazid and pyrazinamide. The molecular structures of the studied compounds depend on the substitution at the N atom adjacent to the carbonyl group. In the case of the unsubstituted derivatives (D1) and (D2), their central frames are generally planar with a twist of the 3,4-dichlorophenyl ring by 30–40°. Until now, coplanarity of the aromatic ring with the (methylene)carbonohydrazone fragment has been considered a prerequisite for tuberculostatic activity. TheN-methylated derivatives (D3) and (D4) show an additional twist along the N—C(=O) bond by 20–30° due to the spatial repulsion introduced by the methyl substituent.

Abstract
ABSTRACT New dimethyl benzoylcarbonohydrazonodithioates were obtained by CS2 addition to arylcarboxylic acid hydrazides and methylation of the formed adduct. The new derivatives were tested for their activity against Mycobacterium tuberculosis. Some compounds exhibited high activity toward sensitive and resistant strains. GRAPHICAL ABSTRACT

Abstract
Four compounds showing moderate antituberculostatic activity have been studied to test the hypothesis that the planarity of the 2-[amino(pyrazin-2-yl)methylidene]dithiocarbazate fragment is crucial for activity. N'-Anilinopyrazine-2-carboximidamide, C(11)H(11)N(5), D1, and diethyl 2,2'-[({[amino(pyrazin-2-yl)methylidene]hydrazinylidene}methylidene)bis(sulfanediyl)]diacetate, C(14)H(19)N(5)O(4)S(2), B1, maintain planarity due to conjugation and attractive intramolecular hydrogen-bond contacts, while methyl 3-[amino(pyrazin-2-yl)methylidene]-2-methyldithiocarbazate, C(8)H(11)N(5)S(2), C1, and benzyl 3-[amino(pyrazin-2-yl)methylidene]-2-methyldithiocarbazate, C(14)H(15)N(5)S(2), C2, are not planar, due to methylation at one of the N atoms of the central N-N bond. The resulting twists of the two molecular halves (parts) of C1 and C2 are indicated by torsion angles of 116.5 (2) and -135.9 (2)°, respectively, compared with values of about 180° in the crystal structures of nonsubstituted compounds. As the methylated derivatives show similar activity against Mycobacterium tuberculosis to that of the nonsubstituted derivatives, maintaining planarity does not seem to be a prerequisite for activity.
